Decrement f, Skip if 0
[ label ] DECFSZ f,d
0 ≤ f ≤ 127
d ∈ [0,1]
(f) - 1 → (destination);
skip if result = 0
None
The contents of register 'f' are
decremented. If 'd' is 0, the result
is placed in the W register. If 'd' is
1, the result is placed back in
register 'f'.
If the result is 1, the next instruc-
tion is executed. If the result is 0,
then a NOP is executed instead,
making it a 2T
Unconditional Branch
[ label ]
0 ≤ k ≤ 2047
k → PC<10:0>
PCLATH<4:3> → PC<12:11>
None
GOTO is an unconditional branch.
The eleven-bit immediate value is
loaded into PC bits <10:0>. The
upper bits of PC are loaded from
PCLATH<4:3>. GOTO is a two-
cycle instruction.
Increment f
[ label ]
0 ≤ f ≤ 127
d ∈ [0,1]
(f) + 1 → (destination)
Z
The contents of register 'f' are
incremented. If 'd' is 0, the result
is placed in the W register. If 'd' is
1, the result is placed back in
register 'f'.

Increment f, Skip if 0
[ label ]
0 ≤ f ≤ 127
d ∈ [0,1]
(f) + 1 → (destination),
None
The contents of register 'f' are
incremented. If 'd' is 0, the result is
placed in the W register. If 'd' is 1,
the result is placed back in
register 'f'.
If the result is 1, the next instruc-

a NOP is executed instead, making
it a 2T
Inclusive OR W with f
[ label ]
0 ≤ f ≤ 127
d ∈ [0,1]
(W) .OR. (f) → (destination)
Z
Inclusive OR the W register with
register 'f'. If 'd' is 0, the result is
placed in the W register. If 'd' is 1,
the result is placed back in
register 'f'.
skip if result = 0
Inclusive OR Literal with W
[ label ]
0 ≤ k ≤ 255
(W) .OR. k → (W)
Z
The contents of the W register are
OR’ed with the eight-bit literal 'k'.
The result is placed in the W
register.
