Example description

This example provides a short description on how to use FLASH Program word mode and Erase byte modes:

• Program a word at a specified address (0x4100).
• Check program word (Read byte).
• Erase word using Erase byte.
• Check erase.

Directory contents

• FLASH\FLASH_WriteWordOperation\main.c Main file containing the "main" function
• FLASH\FLASH_WriteWordOperation\stm8s_conf.h Library Configuration file
• FLASH\FLASH_WriteWordOperation\stm8s_it.c Interrupt routines source
• FLASH\FLASH_WriteWordOperation\stm8s_it.h Interrupt routines declaration

Hardware and Software environment

• This example runs on STM8S and STM8A High density devices.

• This example has been tested with STMicroelectronics STM8/128-EVAL evaluation board and can be easily tailored to any other development board.

How to use it ?

In order to make the program work, you must do the following :

• Copy all source files from this example folder to the template folder under Project
• Open your preferred toolchain
• Rebuild all files and load your image into target memory
• Run the example
• Data read from the data memory is compared with the expected values. The result of this comparison is stored in the "OperationStatus" variable.

Note:

• High-Density STM8A devices are the STM8AF52xx STM8AF6269/8x/Ax, STM8AF51xx, and STM8AF6169/7x/8x/9x/Ax microcontrollers where the Flash memory density ranges between 32 to 128 Kbytes
• Medium-Density STM8A devices are the STM8AF622x/4x, STM8AF6266/68, STM8AF612x/4x, and STM8AF6166/68 microcontrollers where the Flash memory density ranges between 8 to 32 Kbytes
• High-Density STM8S devices are the STM8S207xx, STM8S007 and STM8S208xx microcontrollers where the Flash memory density ranges between 32 to 128 Kbytes.
• Medium-Density STM8S devices are the STM8S105x and STM8S005 microcontrollers where the Flash memory density ranges between 16 to 32-Kbytes.
• Low-Density STM8S devices are the STM8S103xx, STM8S003 and STM8S903xx microcontrollers where the Flash density is 8 Kbytes.
