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 reg-
ister ’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
Complement f

0
d
(f)
Z
The contents of register ’f’ are
complemented. If ’d’ is 0, the
result is stored in W. If ’d’ is 1, the
result is stored back in register ’f’.
Decrement f

d
(f) - 1
Z
Decrement register ’f’. If ’d’ is 0,
the result is stored in the W regis-
ter. If ’d’ is 1, the result is stored
back in register ’f’.

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 regis-
ter ’f’.
If the result is 1, the next instruc-

NOP is executed instead making it
a 2T
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.
