6.2 RESET SEQUENCE MANAGER (RSM)
6.2.1 Introduction
The reset sequence manager includes three RE-
SET sources as shown in
■
■
■
These sources act on the RESET pin and it is al-
ways kept low during the delay phase.
The RESET service routine vector is fixed at ad-
dresses FFFEh-FFFFh in the ST7 memory map.

Caution: When the ST7 is unprogrammed or fully
erased, the Flash is blank and the RESET vector
is not programmed. For this reason, it is recom-
mended to keep the RESET pin in low state until
programming mode is entered, in order to avoid
unwanted behaviour.
