PIC16F193X/LF193X
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 â0â, the result is placed
in the W register. If âdâ is â1â, the result
is placed back in register âfâ.
If the result is â1â, the next instruction is
executed. If the result is â0â, then a
NOP is executed instead, making it a
2-cycle instruction.
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.
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 â0â, the result is placed
in the W register. If âdâ is â1â, the result
is placed back in register âfâ.
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 â0â, the result is placed
in the W register. If âdâ is â1â, the result
is placed back in register âfâ.
If the result is â1â, the next instruction is
executed. If the result is â0â, a NOP is
executed instead, making it a 2-cycle
instruction.
IORLW
Syntax:
Operands:
Operation:
Status Affected:
Description:
Inclusive OR literal with W
[ label ] IORLW k
0 ⤠k ⤠255
(W) .OR. k â (W)
Z
The contents of the W register are
ORâed with the eight-bit literal âkâ. The
result is placed in the W register.
IORWF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Inclusive OR W with f
[ label ] IORWF f,d
0 ⤠f ⤠127
d â [0,1]
(W) .OR. (f) â (destination)
Z
Inclusive OR the W register with regis-
ter âfâ. If âdâ is â0â, the result is placed in
the W register. If âdâ is â1â, the result is
placed back in register âfâ.
