Decrement  contents of Register

The contents of register R will be decremented  by one and  the result is stored  in the same register  R. It is also  an exceptional  case in which  accumulator is not   used  as one of  the operand.  The instruction format is

DCRR                         ( R-R-1)

Flags : All flags  except CY  are modified  according  to the  results
