13. Reset Controller (RSTC)
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 processor
resets.
A brownout detection is also available to prevent the processor from falling into an unpredictable state.
