DECF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Decrement f
[ label ] DECF f,d
0  f  31
d  [0,1]
(f) – 1  (dest)
Z
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’.
DECFSZ
Syntax:
Operands:
Operation:
Status Affected:
Description:
Decrement f, Skip if 0
[ label ] DECFSZ f,d
0  f  31
d  [0,1]
(f) – 1  d; 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 ‘0’, the next instruc-
tion, which is already fetched, is
discarded and a NOP is executed
instead making it a two-cycle
instruction.
GOTO
Syntax:
Operands:
Operation:
Status Affected:
Description:
Unconditional Branch
[ label ] GOTO k
0  k  511
k  PC<8:0>;
STATUS<6:5>  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.

INCF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Increment f
[ label ] INCF f,d
0  f  31
d  [0,1]
(f) + 1  (dest)
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’.
INCFSZ
Syntax:
Operands:
Operation:
Status Affected:
Description:
Increment f, Skip if 0
[ label ] INCFSZ f,d
0  f  31
d  [0,1]
(f) + 1  (dest), skip if result = 0
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 ‘0’, then the next
instruction, which is already
fetched, is discarded and a NOP is
executed instead making it a
two-cycle instruction.
IORLW
Syntax:
Operands:
Operation:
Status Affected:
Description:
Inclusive OR literal with W
[ label ] IORLW k
0  k  255
(W) .OR. (k)  (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.
