The Reset Controller (RSTC), based on power-on reset cells, handles all the resets of the sys-
tem 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.
The Reset Controller is based on two Power-on-Reset cells, one on VDDBU and one on
VDDCORE.
The Reset Controller is capable to return to the software the source of the last reset, either a
general reset (VDDBU rising), a wake-up reset (VDDCORE rising), a software reset, a user
reset or a watchdog reset.
The Reset Controller controls the internal resets of the system and the NRST pin. The NRST pin
is bidirectional. It is handled by the on-chip reset controller and can be driven low to provide a
reset signal to the external components or asserted low externally to reset the microcontroller. It
will reset the Core and the peripherals except the Backup region. There is no constraint on the
length of the reset pulse and the reset controller can guarantee a minimum pulse length.
The NRST pin integrates a permanent pull-up resistor to VDDIOP0 of about 100 kOhms.
The configuration of the Reset Controller is saved as supplied on VDDBU.
