(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 ?

Description: After exchanging the contents of M(DP)
with the contents of register A, an exclusive
OR operation is performed between regis-
ter X and the value j in the immediate field,
and stores the result in register X.
Operation:

Description: After exchanging the contents of M(DP)
with the contents of register A, an exclusive
OR operation is performed between regis-
ter X and the value j in the immediate field,
and stores the result in register X.
Subtracts 1 from the contents of register Y.
As a result of subtraction, when the con-
tents of register Y is 15, the next instruction
is skipped. When the contents of register Y
is not 15, the next instruction is executed.
Operation:
(A)
←→ (M(DP))
(X)
← (X)EXOR(j)
j = 0 to 15

Adds 1 to the contents of register Y. As a re-
sult of addition, when the contents of
register Y is 0, the next instruction is
skipped. when the contents of register Y is
not 0, the next instruction is executed.
