+Method : I
+Description : Handle the bit from the character variables.
+Comments :    The different parameters of commands are
+              - VAR : Name of the character variable where the bit is located.
+              - Place : Bit position in the variable (7 6 5 4 3 2 1 0)
+              - Value : Can be 0 (reset bit) or not 0 (set bit)
+              The "MskBit" command allows to select some bits in a source
+              variables and copy it in a destination var (return the value).
+              The "ValBit" command returns the value of a bit in a char
+              variable: the bit is reset if it returns 0 else the bit is set.
+              This method generates not an optimised code yet.

+Description : Handle directly the bit.
+Comments :    The idea is to handle directly with the bit name. For that, it is

+              This method generates the most optimized code.

+ ****************************************************************************************
+ *
+ *                         I2C State Monitoring Functions
+ *
+ ****************************************************************************************
+ * This I2C driver provides three different ways for I2C state monitoring
+ *  depending on the application requirements and constraints:
+ *
+ *
+ * 1) Basic state monitoring:
+ *    Using I2C_CheckEvent() function:
+ *    It compares the status registers (SR1, SR2 and SR3) content to a given event
+ *    (can be the combination of one or more flags).
+ *    It returns SUCCESS if the current status includes the given flags
+ *    and returns ERROR if one or more flags are missing in the current status.
+ *    - When to use:
+ *      - This function is suitable for most applications as well as for startup
+ *      activity since the events are fully described in the product reference manual
+ *      (RM0016).
+ *      - It is also suitable for users who need to define their own events.
+ *    - Limitations:
+ *      - If an error occurs (ie. error flags are set besides to the monitored flags),
+ *        the I2C_CheckEvent() function may return SUCCESS despite the communication
+ *        hold or corrupted real state.
+ *        In this case, it is advised to use error interrupts to monitor the error
+ *        events and handle them in the interrupt IRQ handler.
+ *
+ *        @note
+ *        For error management, it is advised to use the following functions:
+ *          - I2C_ITConfig() to configure and enable the error interrupts (I2C_IT_ERR).
+ *          - I2C_IRQHandler() which is called when the I2C interrupts occur.
+ *          - I2C_GetFlagStatus() or I2C_GetITStatus() to be called into the
+ *           I2Cx_IRQHandler() function in order to determine which error occurred.
+ *          - I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd()
+ *            and/or I2C_GenerateStop() in order to clear the error flag and
+ *            source and return to correct communication status.
+ *
+ *
+ *  2) Advanced state monitoring:
+ *     Using the function I2C_GetLastEvent() which returns the image of both SR1
+ *     & SR3 status registers in a single word (uint16_t) (Status Register 3 value
+ *     is shifted left by 8 bits and concatenated to Status Register 1).
+ *     - When to use:
+ *       - This function is suitable for the same applications above but it allows to
+ *         overcome the limitations of I2C_GetFlagStatus() function (see below).
+ *         The returned value could be compared to events already defined in the
+ *         library (stm8s_i2c.h) or to custom values defined by user.
+ *       - This function is suitable when multiple flags are monitored at the same time.
+ *       - At the opposite of I2C_CheckEvent() function, this function allows user to
+ *         choose when an event is accepted (when all events flags are set and no
+ *         other flags are set or just when the needed flags are set like
+ *         I2C_CheckEvent() function).
+ *     - Limitations:
+ *       - User may need to define his own events.
+ *       - Same remark concerning the error management is applicable for this
+ *         function if user decides to check only regular communication flags (and
+ *         ignores error flags).
+ *
+ *
+ *  3) Flag-based state monitoring:
+ *     Using the function I2C_GetFlagStatus() which simply returns the status of
+ *     one single flag (ie. I2C_FLAG_RXNE ...).
+ *     - When to use:
+ *        - This function could be used for specific applications or in debug phase.
+ *        - It is suitable when only one flag checking is needed (most I2C events
+ *          are monitored through multiple flags).
+ *     - Limitations:
+ *        - When calling this function, the Status register is accessed. Some flags are
+ *          cleared when the status register is accessed. So checking the status
+ *          of one Flag, may clear other ones.
+ *        - Function may need to be called twice or more in order to monitor one
+ *          single event.

+@REM This batch file has been generated by the IAR Embedded Workbench
+@REM C-SPY Debugger, as an aid to preparing a command line for running
+@REM the cspybat command line utility using the appropriate settings.
+@REM
+@REM Note that this file is generated every time a new debug session
+@REM is initialized, so you may want to move or rename the file before
+@REM making changes.
+@REM
+@REM You can launch cspybat by typing the name of this batch file followed
+@REM by the name of the debug file (usually an ELF/DWARF or UBROF file).
+@REM
+@REM Read about available command line parameters in the C-SPY Debugging
+@REM Guide. Hints about additional command line parameters that may be
+@REM useful in specific cases:
+@REM   --download_only   Downloads a code image without starting a debug
+@REM                     session afterwards.
+@REM   --silent          Omits the sign-on message.
+@REM   --timeout         Limits the maximum allowed execution time.

+@REM This batch file has been generated by the IAR Embedded Workbench

+@REM
+@REM Note that this file is generated every time a new debug session

+@REM
+@REM You can launch cspybat by typing the name of this batch file followed

+ This driver provides functions to configure and program the Flash memory of all
+ STM8S devices.
+
+ It includes as well functions that can be either executed from RAM or not, and
+ other functions that must be executed from RAM otherwise useless.
+
+ The table below lists the functions that can be executed from RAM.
+
+ +--------------------------------------------------------------------------------|
+ |   Functions prototypes      |    RAM execution            |     Comments       |
+ ---------------------------------------------------------------------------------|
+ |                             | Mandatory in case of block  | Can be executed    |
+ | FLASH_WaitForLastOperation  | Operation:                  | from Flash in case |
+ |                             | - Block programming         | of byte and word   |
+ |                             | - Block erase               | Operations         |
+ |--------------------------------------------------------------------------------|
+ | FLASH_ProgramBlock          |       Exclusively           | useless from Flash |

+ | FLASH_EraseBlock            |       Exclusively           | useless from Flash |
+ |--------------------------------------------------------------------------------|
+
+ To be able to execute functions from RAM several steps have to be followed.
+ These steps may differ from one toolchain to another.
+ A detailed description is available below within this driver.
+ You can also refer to the FLASH examples provided within the
+ STM8S_StdPeriph_Lib package.

+ All the functions defined below must be executed from RAM exclusively, except

+
+ Steps of the execution from RAM differs from one toolchain to another:
+ - For Cosmic Compiler:
+    1- Define a segment FLASH_CODE by the mean of " #pragma section (FLASH_CODE)".
+    This segment is defined in the stm8s_flash.c file.
+  2- Uncomment the "#define RAM_EXECUTION  (1)" line in the stm8s.h file,
+    or define it in Cosmic compiler preprocessor to enable the FLASH_CODE segment
+   definition.
+  3- In STVD Select Project\Settings\Linker\Category "input" and in the RAM section
+    add the FLASH_CODE segment with "-ic" options.
+  4- In main.c file call the _fctcpy() function with first segment character as 
+    parameter "_fctcpy('F');" to load the declared moveable code segment
+    (FLASH_CODE) in RAM before execution.
+  5- By default the _fctcpy function is packaged in the Cosmic machine library,
+    so the function prototype "int _fctcopy(char name);" must be added in main.c
+    file.
+
+  - For Raisonance Compiler
+   1- Use the inram keyword in the function declaration to specify that it can be
+    executed from RAM.
+    This is done within the stm8s_flash.c file, and it's conditioned by 
+    RAM_EXECUTION definition.
+   2- Uncomment the "#define RAM_EXECUTION  (1)" line in the stm8s.h file, or 
+   define it in Raisonance compiler preprocessor to enable the access for the 
+   inram functions.
+   3- An inram function code is copied from Flash to RAM by the C startup code. 
+   In some applications, the RAM area where the code was initially stored may be
+   erased or corrupted, so it may be desirable to perform the copy again. 
+   Depending on the application memory model, the memcpy() or fmemcpy() functions
+   should be used to perform the copy.
+      • In case your project uses the SMALL memory model (code smaller than 64K),
+       memcpy()function is recommended to perform the copy
+      • In case your project uses the LARGE memory model, functions can be 
+      everywhere in the 24-bits address space (not limited to the first 64KB of
+      code), In this case, the use of memcpy() function will not be appropriate,
+      you need to use the specific fmemcpy() function (which copies objects with
+      24-bit addresses).
+      - The linker automatically defines 2 symbols for each inram function:
+           • __address__functionname is a symbol that holds the Flash address 
+           where the given function code is stored.
+           • __size__functionname is a symbol that holds the function size in bytes.
+     And we already have the function address (which is itself a pointer)
+  4- In main.c file these two steps should be performed for each inram function:
+     • Import the "__address__functionname" and "__size__functionname" symbols
+       as global variables:
+         extern int __address__functionname; // Symbol holding the flash address
+         extern int __size__functionname;    // Symbol holding the function size
+     • In case of SMALL memory model use, Call the memcpy() function to copy the
+      inram function to the RAM destination address:
+                memcpy(functionname, // RAM destination address
+                      (void*)&__address__functionname, // Flash source address
+                      (int)&__size__functionname); // Code size of the function
+     • In case of LARGE memory model use, call the fmemcpy() function to copy 
+     the inram function to the RAM destination address:
+                 memcpy(functionname, // RAM destination address
+                      (void @far*)&__address__functionname, // Flash source address
+                      (int)&__size__functionname); // Code size of the function
+
+ - For IAR Compiler:
+    1- Use the __ramfunc keyword in the function declaration to specify that it 
+    can be executed from RAM.
+    This is done within the stm8s_flash.c file, and it's conditioned by 
+    RAM_EXECUTION definition.
+    2- Uncomment the "#define RAM_EXECUTION  (1)" line in the stm8s.h file, or 
+   define it in IAR compiler preprocessor to enable the access for the 
+   __ramfunc functions.
+
+ - Note: 
+    1- Ignore the IAR compiler warnings, these warnings don't impact the FLASH Program/Erase
+    operations.
+    The code performing the Flash Program/erase must be executed from RAM; the variables
+    initializations don't necessary require the execution from RAM, only CR2/NCR2 registers 
+    configuration and data programing must be executed from RAM.
+    2- These warnings depends on IAR compiler: as the code generation is made using many
+    runtime library functions to keep code size to a minimum.
+    3- It is recommended to use High Speed Optimization with IAR (-Ohs), in order 
+    to reduce the runtime library calls in the generated code.
+
+
+
+ The FLASH examples given within the STM8S_StdPeriph_Lib package, details all 
+ the steps described above.

+ *
+ *                         I2C State Monitoring Functions
+ *
+ ****************************************************************************************
+ * This I2C driver provides three different ways for I2C state monitoring
+ *  depending on the application requirements and constraints:
+ *
+ *
+ * 1) Basic state monitoring:
+ *    Using I2C_CheckEvent() function:
+ *    It compares the status registers (SR1, SR2 and SR3) content to a given event
+ *    (can be the combination of one or more flags).
+ *    It returns SUCCESS if the current status includes the given flags
+ *    and returns ERROR if one or more flags are missing in the current status.
+ *    - When to use:
+ *      - This function is suitable for most applications as well as for startup
+ *      activity since the events are fully described in the product reference manual
+ *      (RM0016).
+ *      - It is also suitable for users who need to define their own events.
+ *    - Limitations:
+ *      - If an error occurs (ie. error flags are set besides to the monitored flags),
+ *        the I2C_CheckEvent() function may return SUCCESS despite the communication
+ *        hold or corrupted real state.
+ *        In this case, it is advised to use error interrupts to monitor the error
+ *        events and handle them in the interrupt IRQ handler.
+ *
+ *        @note
+ *        For error management, it is advised to use the following functions:
+ *          - I2C_ITConfig() to configure and enable the error interrupts (I2C_IT_ERR).
+ *          - I2C_IRQHandler() which is called when the I2C interrupts occur.
+ *          - I2C_GetFlagStatus() or I2C_GetITStatus() to be called into the
+ *           I2C_IRQHandler() function in order to determine which error occurred.
+ *          - I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd()
+ *            and/or I2C_GenerateStop() in order to clear the error flag and
+ *            source and return to correct communication status.
+ *
+ *
+ *  2) Advanced state monitoring:
+ *     Using the function I2C_GetLastEvent() which returns the image of both SR1
+ *     & SR3 status registers in a single word (uint16_t) (Status Register 3 value
+ *     is shifted left by 8 bits and concatenated to Status Register 1).
+ *     - When to use:
+ *       - This function is suitable for the same applications above but it allows to
+ *         overcome the limitations of I2C_GetFlagStatus() function (see below).
+ *         The returned value could be compared to events already defined in the
+ *         library (stm8s_i2c.h) or to custom values defined by user.
+ *       - This function is suitable when multiple flags are monitored at the same time.
+ *       - At the opposite of I2C_CheckEvent() function, this function allows user to
+ *         choose when an event is accepted (when all events flags are set and no
+ *         other flags are set or just when the needed flags are set like
+ *         I2C_CheckEvent() function).
+ *     - Limitations:
+ *       - User may need to define his own events.
+ *       - Same remark concerning the error management is applicable for this
+ *         function if user decides to check only regular communication flags (and
+ *         ignores error flags).
+ *
+ *
+ *  3) Flag-based state monitoring:
+ *     Using the function I2C_GetFlagStatus() which simply returns the status of
+ *     one single flag (ie. I2C_FLAG_RXNE ...).
+ *     - When to use:
+ *        - This function could be used for specific applications or in debug phase.
+ *        - It is suitable when only one flag checking is needed (most I2C events
+ *          are monitored through multiple flags).
+ *     - Limitations:
+ *        - When calling this function, the Status register is accessed. Some flags are
+ *          cleared when the status register is accessed. So checking the status
+ *          of one Flag, may clear other ones.
+ *        - Function may need to be called twice or more in order to monitor one
+ *          single event.
+ *
+ *  For detailed description of Events, please refer to section I2C_Events in
+ *  stm8s_i2c.h file.
