The program counter and the high-order 4 bits of PSW are stored in address indicated by stack pOinter(SP). SP is incremented by 1 and m is transferred to PCo-PC 1O•SP is decremented by 1. Program counter is restored to saved setting in stack indicated by stack pOinter. PSW4-PSW7 are not changedand interrupt disable is maintained.SP is decremented by 1. Program counter and high-order 4 bits of PSW are restored with saved data in stack indicated by stack pOinter.Interrupt becomes enabled after execution is completed.Loads contents of Pp to register A.Output latches contents of register A to Pp.Logical product of contents of Pp and data n; outputs result to Pp.Logical sum of contents of Pp and data n; outputs result to Pp.Enters contents of data bus buffer (DBB) into register A and resets IBF.Outputs contents of register A to data bus buffer (DBB) and sets OBF.• MITSUBISHI....
