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 2 T
Unconditional Branch

PCLATH<4:3>
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

d
(f) + 1
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'.
