EWDT
Enable Watchdog (R/W).
bit 7
Write 1/Write 0 sequence sets the Watchdog Enable Counting bit.
DWDT
Disable Watchdog (R/W).
bit 6
Write 1/Write 0 sequence clears the Watchdog Enable Counting bit.
RWDT
Reset Watchdog (R/W).
bit 5
Write 1/Write 0 sequence restarts the Watchdog Counter.
WDCNT40 Watchdog Count (R/W).
bits 40
Watchdog expires in (WDCNT + 1)
HMSEC to (WDCNT + 2) HMSEC, if the sequence is not asserted. There is
an uncertainty of 1 count.
NOTE: If HCR0.3 (EWDR) is set and the watchdog timer expires, a system reset is generated. If HCR0.3 (EWDR) is
cleared and the watchdog timer expires, an interrupt is generated (see Table 6).
