NRSTB
The NRSTB pin is an asynchronous reset input, which acts exactly like the zero-power power-on
reset cell.
As soon as NRSTB is tied to GND, the supply controller is reset generating in turn, a reset of the
whole system.
When NRSTB is released, the system can start as described in
Backup Power
The NRSTB pin does not need to be driven during power-up phase to allow a reset of the sys-
tem, it is done by the zero-power power-on cell.
As shown in
the SHDN pin to control external voltage regulator with shutdown capabilities.
The Supply Controller manages the vddcore_nreset signal to the Reset Controller, as described
previously in
mally asserted before shutting down the core power supply and released as soon as the core
power supply is correctly regulated.
There are two additional sources which can be programmed to activate vddcore_nreset:
The supply monitor is capable of generating a reset of the system. This can be enabled by set-
ting the SMRSTEN bit in the Supply Controller Supply Monitor Mode Register (SUPC_SMMR).
If SMRSTEN is set and if a supply monitor detection occurs, the vddcore_nreset signal is imme-
diately activated for a minimum of 1 slow clock cycle.

• a brownout detection
