Zynq UltraScale+ MPSoCs have two system watchdog timers, one each for full-power domain (FPD) and low-power domain (LPD). Each of these WDT provides error condition information to the error manager. EM module can be configured to set a specific error action when FPD or LPD WDT expires. This section describes the usage of these watchdog timers and the PMU firmware functionality when these watchdog timers expire.
