The 8085 microprocessor has two instructions to implement subroutines: CALL (call a subroutine), and RET (return to main program from a subroutine). The CALL instruction interrupts the flow of an exec by passing control to an internal or external subroutine. An internal subroutine is part of the calling This group includes the instructions for conditional and unconditional jump, subroutine call and return, and restart. Examples are: JMP, JC, JZ, CALL, CZ,Solution Show Solution · 1) CC addr : Call if carry (Cy = 1) · 2) CNC addr : Call if no carry (Cy = 0) · 3) CZ addr : Call if zero (Z = 1) · 4) CNZ addr : Callif no Some instructions use a combination of addressing modes. A CALL instruction, for example, combines direct addressing and register indirect addressing. The Call Instruction, CC, CNC, CP, CM, CZ, CNZ, CPE, CPO · 1. CC: - (conditional call) The program sequence is transferred to a particular level or a 16-bit address
