Example

Increment f, Skip if 0

[ label ] INCFSZ f,d

0 ≤ f ≤ 127

d ∈ [0,1]

(f) + 1 → (dest), skip if result = 0

None

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 instruc-

tion, which is already fetched, is

discarded. A NOP is executed

instead making it a two-cycle

instruction.

1000 kkkk kkkk

The contents of the W register is

OR’ed with the eight bit literal 'k'.

The result is placed in the W

register.
