For zero flag - return instructions, Electrical Engineering

For zero flag

 RZ ( Return on Zero) and RNZ ( Return on no zero) Instructions

RZ  returns from the subroutine to the  calling  program, if zero flag  is set  (Z= 1). The instruction format is

                                 RZ

RNZ returns  from the  subroutine the  calling program if zero  flag is not set  (Z= 0). The instruction format is

                                 RNZ
