Example

Increment f

[ label ] INCF f,d

0 ≤ f ≤ 127

d ∈ [0,1]

(f) + 1 → (dest)

Z

00

1010 dfff ffff

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

Increment f, Skip if 0

[ label ] INCFSZ f,d

0 ≤ f ≤ 127

d ∈ [0,1]

(f) + 1 → (dest), skip if result = 0

None

00

1111 dfff ffff

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, the next

instruction, which is already

fetched, is discarded. A NOP is

executed instead making it a

two-cycle instruction.
