Each CPU has a watchdog timer that can optionally trigger a reset that lasts for 512 INTOSC1 cycles. CPU1 watchdog reset (CPU1.WDRS) produces an XRS. CPU2 watchdog reset (CPU2.WDRS) produces a CPU2.SYSRS and triggers an NMI on CPU1.
After a watchdog reset, the WDRSn bit in RESC is set. Software can read this bit to know the cause of reset and clear the status by writing 1 into corresponding bit in RESCCLR register.
