Question: How to delay this code from 1 second delay to 0.5second delay?
org 0000h;
ljmp main;
org 0050h;
main:
    mov dptr,#SMG_DUAN ;
   mov r0,#00h;
   mov r1,#0ah;
lin1:mov a,r0;
   movc a,@a+dptr; get first indexed data in romto accumolator a
   mov p1,a; move data in a to port 1
   lcall delay; subroutine call for thedelay
   inc r0; increase r0 by one to get to the nextindex
   djnz r1,lin1; repeat the above instructionstill we get all the data
   sjmp main;
delay:
mov r3,#0fh; move 0fh to regester 3
lin2: mov r4,#0ffh; mov 0ff to reginster 4
lin3: mov r5,#0ffh; move 0ff to register 5
djnz r5,$; decrease r5 till it equal to 0
djnz r4,lin3; decrease r4 till it equal to 0
djnz r3,lin2; decrease r3 till it equal to 0
