Decrement f
[ label ] DECF f,d
0
d
(f) – 1
Decrement register ‘f’. If ‘d’ is ‘0’,
the result is stored in the W
register. If ‘d’ is ‘1’, the result is
stored back in register ‘f’.
Decrement f, Skip if 0
[ label ] DECFSZ f,d
0
d
(f) – 1
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 ‘0’, the next instruc-
tion, which is already fetched, is
discarded and a NOP is executed
instead making it a two-cycle
instruction.
Unconditional Branch
[ label ]
0
k
STATUS <6:5>
GOTO is an unconditional branch.
The 9-bit immediate value is
loaded into PC bits <8:0>. The
upper bits of PC are loaded from
STATUS <6:5>. GOTO is a two-
cycle instruction.

Increment f
[ label ]

d
(f) + 1
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’.
[ label ]
0
d
(f) + 1
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 ‘0’, then the next
instruction, which is already
fetched, is discarded and a NOP is
executed instead making it a
two-cycle instruction.
Inclusive OR literal with W
[ label ]
0
(W) .OR. (k)
The contents of the W register are
OR’ed with the eight-bit literal ‘k’.
The result is placed in the
W register.
