Symbol
Function
WDTON
Watchdog timer start control bit (Used in Watchdog mode)
0: Watchdog timer can be started or stopped freely during Watchdog mode.
1: Start Watchdog timer; bit cannot be cleared by software.
WDFE
Watchdog feed sequence error flag
0: Watchdog feed sequence error has not occurred.
1: Due to an incorrect feed sequence before writing to WDTC in Watchdog mode, the
hardware entered Watchdog reset and set this flag to “1.” This is for software to detect
whether the Watchdog reset was caused by timer expiration or an incorrect feed
sequence.
WDRE
Watchdog timer reset enable.
0: Disable Watchdog timer reset.
1: Enable Watchdog timer reset.
WDTS
Watchdog timer reset flag.
0: External hardware reset or power-on reset clears the flag.
Flag can also be cleared by writing a 1.
Flag survives if chip reset happened because of Watchdog timer overflow.
1: Hardware sets the flag on watchdog overflow.
WDT
Watchdog timer refresh.
0: Hardware resets the bit when refresh is done.
1: Software sets the bit to force a Watchdog timer refresh.
SWDT
Start Watchdog timer.
0: Stop WDT.
1: Start WDT.
