DECFSZ
Decrement f, Skip if 0
Syntax:
Operands:
Operation:
Status Affected:
Description:
[ label ] DECFSZ f,d
0 f 127
d [0,1]
(f) - 1 (destination);
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 ‘1’, the next
instruction is executed. If the
result is ‘0’, 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 PC<10:0>
PCLATH<4:3> 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 [0,1]
(f) + 1 (destination)
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
Increment f, Skip if 0
Syntax:
Operands:
Operation:
Status Affected:
Description:
[ label ] INCFSZ f,d
0 f 127
d [0,1]
(f) + 1 (destination),
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 ‘1’, the next
instruction is executed. If the
result is ‘0’, 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 (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.
IORWF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Inclusive OR W with f
[ label ] IORWF f,d
0 f 127
d [0,1]
(W) .OR. (f) (destination)
Z
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’.
