skip if result = 0
None
The contents of register ‘f’ are
decremented. If ‘d’ = 0, the result
is placed in the W register. If
‘d’ = 1, the result is placed back in
register ‘f’.
If the result is ‘1’, the next
instruction is executed. If the
result is ‘0’, then a NOP is
executed instead, making it a
2 T
Complement f

(f)
Z
The contents of register ‘f’ are
complemented. If ‘d’ = 0, the
result is stored in W. If ‘d’ = 1, the
result is stored back in register ‘f’.
Decrement f
[ label ] DECF f,d
0
d
(f) – 1
Z
Decrement register ‘f’. If ‘d’ = 0,
the result is stored in the W
register. If ‘d’ = 1, the result is
stored back in register ‘f’.

None
The contents of register ‘f’ are
incremented. If ‘d’ = 0, the result is
placed in the W register. If ‘d’ = 1,
the result is placed back in
register ‘f’.
If the result is ‘1’, the next
instruction is executed. If the
result is ‘0’, a NOP is executed
instead, making it a 2 T
instruction.
Unconditional Branch

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.
