(f) + 1
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’.

(f) + 1
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 0, then the next instruc-
tion, which is already fetched, is dis-
carded and an NOP is executed
instead making it a two cycle instruc-
tion.
