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’.
INCF
Syntax:

Increment f
[

d
∈
[0,1]
(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’.

d;
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 ‘0’, the next instruc-
tion, which is already fetched, is
discarded and a
NOP
is executed
instead making it a two-cycle
instruction.

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.

PC<10:9>
None
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.
IORLW

(W)
Z
The contents of the W register are
OR’ed with the eight-bit literal ‘k’.
The result is placed in the W
register.
