Discussion : 1. For each program given below, specify the resulting contents of any affected registers. Draw a memory map showing the stack locations used and their final contents. a) MOV SP, 2450h b) MOV SP, 2415h MOV BX, 2460h MOV DX, 1234 h PUSH BX PUSH DX 2. What is the main reason to use a stack? Explain the principle operation of stack in 8086. 3. Write an 8086 program to count up from 00 to 60 in precise time delay intervals. The delay is to be carried out in a subroutine and the delay time parameter is to be passed to it in register BL
