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 regis-
ter '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 2T
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 2T
CY
instruction
.
