None
The contents of register ’f’ are
decremented. If ’d’ is 0, the result
is placed in the W register. If ’d’ is
1, the result is placed back in reg-
ister ’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.
