Reset sequence manager (RSM)
Introduction
The reset sequence manager includes three RESET sources as shown in
●
●
●
A reset can also be triggered following the detection of an illegal opcode or prebyte code.
Refer to
These sources act on the RESET pin and it is always kept low during the delay phase.
The RESET service routine vector is fixed at addresses FFFEh-FFFFh in the ST7 memory
mapping.
The basic RESET sequence consists of 3 phases as shown in
