The contents of register ’f’ are decre-
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, the next instruc-
tion, which is already fetched, is
discarded. A NOP is executed
instead making it a two-cycle
instruction.
