Decrement register ’f’. If ’d’ is 0, the
result is stored in the W register. If ’d’
is 1, the result is stored back in
register ’f’.

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 1, the next instruction is
executed. If the result is 0, then a NOP
is executed instead, making it a 2T
instruction.
