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
instruction is executed. If the result
is ‘0’, then a NOP is executed
instead, making it a 2-cycle
instruction.
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

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’.

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
instruction is executed. If the
result is ‘0’, a NOP is executed
instead, making it a 2-cycle
instruction.
skip if result = 0
Move f
[ label ]

d
(f)
Z
The contents of register ‘f’ are
moved to a destination
dependent upon the status of ‘d’.
If ‘d’ = 0, destination is W register.
If ‘d’ = 1, the destination is file
register ‘f’ itself. ‘d’ = 1 is useful to
test a file register since status flag
Z is affected.
