This application note explains the different kinds of reset available on ST10F269/ST10F280 and compares ST10F269/ST10F280 reset features with ST10F168 ones.
This document serves as an application note for hardware designers working with the ST10F269 and ST10F280 microcontrollers. It details the various types of system resets available, including asynchronous hardware, synchronous short/long hardware, software, and watchdog resets. The text compares these features to the previous ST10F168 generation.
The device supports asynchronous hardware reset, synchronous short and long hardware resets, software reset via SRST instruction, and watchdog timer reset.
The WDTCON register contains specific flags for each reset source, which are cleared when the EINIT instruction is executed.
An asynchronous reset uses a low level on the RPD pin, while a synchronous reset uses a high level on the RPD pin when asserting RSTIN.
