Q Cycle Activity:

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 incre-

mented. 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 1, the next instruction is

executed. If the result is 0, a NOP is

executed instead making it a 2TCY

instruction.
