BITS DESCRIPTIONS

[6]

WTIE

Watchdog Timer Interrupt Enable

0 = Disable the Watchdog timer interrupt

1 = Enable the Watchdog timer interrupt

[5:4]

WTIS

Watchdog Timer Interval Select

These two bits select the interval for the Watchdog timer. No matter

which interval is chosen, the reset timeout is always occurred 512

WDT clock cycles later than the interrupt timeout.

WTIF

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. If

the Watchdog timer interrupt is not enabled, then this bit indicates that

a timeout period has elapsed.

0 = Watchdog timer interrupt does not occur

1 = Watchdog timer interrupt occurs

NOTE: This bit is read only, but can be cleared by writing 1 to this bit.

WTRF

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 up manually. If WTRE is

disabled, then the Watchdog timer has no effect on this bit.

0 = Watchdog timer reset does not occur

1 = Watchdog timer reset occurs

NOTE: This bit is read only, but can be cleared by writing 1 to this bit.
