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 register 'f'.
If the result is 0, then the next instruction (fetched during the current
instruction execution) is discarded and a NOP is executed instead, mak-
ing this a 2 cycle instruction.
