13. Reset Controller (RSTC)
13.1
13.2
Overview
The Reset Controller (RSTC), based on power-on reset cells, handles all the resets of the system without any
external components. It reports which reset occurred last.
The Reset Controller also drives independently or simultaneously the external reset and the peripheral and proces-
sor resets.
A brownout detection is also available to prevent the processor from falling into an unpredictable state.
