PIC16C745/765
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
complemented. 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 regis-
ter. 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
decremented. If 'd' is 0, the result
is placed in the W register. If 'd' is
1, the result is placed back in reg-
ister 'f'.
If the result is 1, the next instruc-
tion 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
incremented. If 'd' is 0, the result
is placed in the W register. If 'd' is
1, the result is placed back in reg-
ister '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
incremented. If 'd' is 0, the result is
placed in the W register. If 'd' is 1,
the result is placed back in regis-
ter 'f'.
If the result is 1, the next instruc-
tion is executed. If the result is 0, a
NOP is executed instead making it
a 2T
CY instruction.
