23.4.7 Security Module

Both watchdogs are connected to the security module. If a down counter reaches 0, an alarm is systematically sent to the security module (whatever the configuration of interrupts and resets).

If the PSWDT is restarted before the RPTH threshold, an alarm is sent to the security module only if PS_WDT_MR.RPTHRST is set to ‘1’. Nevertheless, this does not cancel the reset operation.
