Decrement register ‘R’. If ‘d’ is 0 the result is stored in the ACC register. If ‘d’ is 1 the result is
stored back in register ‘R’.

None
The contents of register ‘R’ are decremented. If ‘d’ is 0 the result is placed in the ACC
register. If ‘d’ is 1 the result is placed back in register ’R’.
If the result is 0, the next instruction, which is already fetched, is discarded and a NOP is
executed instead making it a two-cycle instruction.
