(WDF1) = 1
Grouping:
Other operation
Description: Clears (0) to the WDF1 flag and skips the
next instruction when watchdog timer flag
WDF1 is “1.” When the WDF1 flag is “0,” ex-
ecutes the next instruction. Also, stops the
watchdog timer function when executing the
WRST instruction immediately after the
DWDT instruction.
Operation:
(WDF1) = 1 ?
(WDF1) ← 0
