INCF
Increment f
Syntax:
[ label ] INCF f,d
Operands:
0 ≤ f ≤ 31
d ∈ [0,1]
Operation:
(f) + 1 → (dest)
Status Affected: Z
Encoding:
0010 10df ffff
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 register
’f’.

Example:
INCF CNT, 1
Before Instruction
CNT = 0xFF
Z
=0
After Instruction
CNT = 0x00

INCFSZ
Increment f, Skip if 0
Syntax:
[ label ] INCFSZ f,d
Operands:
0 ≤ f ≤ 31
d ∈ [0,1]
Operation:
(f) + 1 → (dest), skip if result = 0
Status Affected: None
Encoding:
0011 11df ffff
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 register
’f’.
If the result is 0, then the next
instruction, which is already
fetched, is discarded and a NOP is
executed instead making it a two
cycle instruction.
