PM0051 Datasheet PDF - STMicroelectronics

Introduction
   This manual describes how to program Flash program memory and data EEPROM on STM8 microcontrollers. It applies to access and performance line STM8S and medium and high density STM8A devices. It is intended to provide information to the programming tool manufacturers and to the customers who want to implement programming by themselves on their production line.

   The in-circuit programming (ICP) method is used to update the content of Flash program memory and data EEPROM while the user software is not running. It uses the Single wire interface module (SWIM) to communicate between the programming tool and the device.
