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
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 2TCY instruction.
GOTO
Unconditional Branch
Syntax:
[
label ]
GOTO k
Operands:
0
≤ k ≤ 2047
Operation:
k
→ PC<10:0>
PCLATH<4:3>
→ PC<12:11>
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
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
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
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 instruc-
tion is executed. If the result is 0,
a NOP is executed instead, making
it a 2TCY 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
register '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'.
