Dear fans,
I am feeling a problem, code given below set my problem.
Case 1:
increment: add al, 1
mov dx, 0x37A
mov al, 1
; problem here arises as (mov al, 1)that i want to set bit 1 to
;control pin C0 to one how i can set it.
out dx, al
cmp al, 21
jne increment
jmp terminate:
Case 2:
decrement: sub al, 0
mov dx, 0x37A
mov al, 0
out dx, al
; problem here arises as (mov al, 0)that i want to set bit 0 to
;control pin C1 to zero how i can set it.
cmp al, 21
jne decrement
jmp terminate:
i am too much confuse kindly solve this issue.
