Register 5: WatchDog Timer Time-Out Trigger Status (WDTTR)

OFFSET = 0x010
WDTTR saves the occurrence times of watchdog timer time-out. The corresponding
operation differs from the access type which is taken on WDTTR. A read-out from
WDTTR would clear the watchdog interrupt while a write-in clear WDTTR.

B.1.6 Register 6: WatchDog Timer Interrupt Control Register
(WDTINTCTR)
OFFSET = 0x014
Based on the watchdog timer time-out frequency which is stored in WDTTR,
WDTINTCTR sets the period of interrupt. WDTTR plus one as watchdog timer time
out occurred. While the number of occurrences exceeds the value saved in
WDTINTCTR, an interrupt would be issued.
