COMF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Complement f
[ label ] COMF f,d
0 ⤠f ⤠127
d â [0,1]
(f) â (destination)
Z
The contents of register âfâ are comple-
mented. If âdâ is 0, the result is stored
in W. If âdâ is 1, the result is stored
back in register âfâ.
GOTO
Syntax:
Operands:
Operation:
Status Affected:
Description:
Unconditional Branch
[ label ] GOTO k
0 ⤠k ⤠2047
k â PC<10:0>
PCLATH<4:3> â PC<12:11>
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.
DECF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Decrement f
[label] DECF f,d
0 ⤠f ⤠127
d â [0,1]
(f) - 1 â (destination)
Z
Decrement register âfâ. If âdâ is 0, the
result is stored in the W register. If âdâ
is 1, the result is stored back in
register âfâ.
INCF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Increment f
[ label ] INCF f,d
0 ⤠f ⤠127
d â [0,1]
(f) + 1 â (destination)
Z
The contents of register âfâ are incre-
mented. If âdâ is 0, the result is placed
in the W register. If âdâ is 1, the result is
placed back in register âfâ.
DECFSZ
Syntax:
Operands:
Operation:
Status Affected:
Description:
Decrement f, Skip if 0
[ label ] DECFSZ f,d
0 ⤠f ⤠127
d â [0,1]
(f) - 1 â (destination);
skip if result = 0
None
The contents of register âfâ are decre-
mented. If âdâ is 0, the result is placed
in the W register. If âdâ is 1, the result is
placed back in register âfâ.
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 TCY
instruction.
INCFSZ
Syntax:
Operands:
Operation:
Status Affected:
Description:
Increment f, Skip if 0
[ label ] INCFSZ f,d
0 ⤠f ⤠127
d â [0,1]
(f) + 1 â (destination),
skip if result = 0
None
The contents of register âfâ are incre-
mented. If âdâ is 0, the result is placed
in the W register. If âdâ is 1, the result is
placed back in register âfâ.
If the result is 1, the next instruction is
executed. If the result is 0, a NOP is
executed instead making it a 2 TCY
instruction.
