Series Technical Reference Manual
Watchdog Timer Enable (write protection bits)
0 = Disable the Watchdog timer (This action will reset the internal counter)
1 = Enable the Watchdog timer
Watchdog Timer Interrupt Enable (write protection bits)
0 = Disable the Watchdog timer interrupt
1 = Enable the Watchdog timer interrupt
Watchdog Timer Wakeup Flag
If Watchdog timer causes CPU wakes up from power-down mode, this bit will
be set to high.
0 = Watchdog timer does not cause CPU wakeup.
1 = CPU wake up from sleep or power-down mode by Watchdog timeout.
NOTE: Write 1 to clear this bit to zero.
Watchdog Timer Wakeup Function Enable bit
0 = Disable Watchdog timer Wakeup CPU function.
1 = Enable the Wakeup function that Watchdog timer timeout can wake up CPU
Watchdog Timer Interrupt Flag
If the Watchdog timer interrupt is enabled, then the hardware will set this bit to
indicate that the Watchdog timer interrupt has occurred.
0 = Watchdog timer interrupt did not occur
1 = Watchdog timer interrupt occurs
NOTE: Write 1 to clear this bit to zero.
Watchdog Timer Reset Flag
When the Watchdog timer initiates a reset, the hardware will set this bit. This
flag can be read by software to determine the source of reset. Software is
responsible to clear it manually by writing 1 to it. If WTRE is disabled, then the
Watchdog timer has no effect on this bit.
0 = Watchdog timer reset did not occur
1 = Watchdog timer reset occurs
