Using 8086 microprocessor generate a square wave by using internal DAC0808. Show the result on oscilloscopeTimehigh=5sec,Timelow=2sec. With assembly language.

I dont know how i can transform 5 and 2 seconds to hex for this cpu.

We made up to this:

CODE SEGMENT ASSUME CS:CODE,DS:CODE

ORG 0

START: MOV DX,3FD8H XOR AL,AL UP: MOV AL,0FFH OUT DX,AL MOV CX,0A0H LOOP $ DOWN: MOV AL,00H OUT DX,AL MOV CX,0A0H LOOP $

JMP UP

CODE ENDS END START
