PIC16C63A/65B/73B/74B
COMF Complement f
Syntax: [ label ] COMF f,d
Operands: 0 f 127
d [0,1]
Operation: (f
) (destination)
Status Affected: Z
Description:
The contents of register 'f' are comple-
mented. If 'd' is 0, the result is stored
in W. If 'd' is 1, the result is stored
back in register 'f'.
DECF Decrement f
Syntax: [label] DECF f,d
Operands: 0 f 127
d [0,1]
Operation: (f) - 1 (destination)
Status Affected: Z
Description:
Decrement register 'f'. If 'd' is 0, the
result is stored in the W register. If 'd'
is 1, the result is stored back in
register 'f'.
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 T
CY
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 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 T
CY
instruction
