PIC16F72
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’ = ‘0’, the
result is stored in W. If ‘d’ = ‘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’ = ‘0’,
the result is stored in the W
register. If ‘d’ = ‘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’ = ‘0’, the result
is placed in the W register. If
‘d’ = ‘1’, the result is placed back
in register ‘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 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
incremented. If ‘d’ = ‘0’, the result
is placed in the W register. If
‘d’ = ‘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
incremented. If ‘d’ = ‘0’, the result
is placed in the W register. If
‘d’ = ‘1’, the result is placed back
in register ‘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 2 T
CY instruction.
