DECFSZ
Decrement f, Skip if 0
Syntax:
[ label ] DECFSZ f,d
Operands:
0
f 127
d
[0,1]
Operation:
(f) - 1
(destination);
skip if result = 0
Status Affected:
None
Description:
The contents of register ‘f’ are decre-
mented. 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.
GOTO
Unconditional Branch
Syntax:
[ label ]
GOTO k
Operands:
0
k 2047
Operation:
k
PC<10:0>
PCLATH<6:3>
PC<14:11>
Status Affected:
None
Description:
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.
INCF
Increment f
Syntax:
[ label ]
INCF f,d
Operands:
0
f 127
d
[0,1]
Operation:
(f) + 1
(destination)
Status Affected:
Z
Description:
The contents of register ‘f’ are incre-
mented. 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
Increment f, Skip if 0
Syntax:
[ label ]
INCFSZ f,d
Operands:
0
f 127
d
[0,1]
Operation:
(f) + 1
(destination),
skip if result = 0
Status Affected:
None
Description:
The contents of register ‘f’ are incre-
mented. 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.
IORLW
Inclusive OR literal with W
Syntax:
[ label ]
IORLW k
Operands:
0
k 255
Operation:
(W) .OR. k
(W)
Status Affected:
Z
Description:
The contents of the W register are
OR’ed with the eight-bit literal ‘k’. The
result is placed in the W register.
IORWF
Inclusive OR W with f
Syntax:
[ label ]
IORWF
f,d
Operands:
0
f 127
d
[0,1]
Operation:
(W) .OR. (f)
(destination)
Status Affected:
Z
Description:
Inclusive OR the W register with regis-
ter ‘f’. If ‘d’ is ‘0’, the result is placed in
the W register. If ‘d’ is ‘1’, the result is
placed back in register ‘f’.
