    What type of delay could you use here,
    I thought
    Timer 0 Mode 2 in an 8051

    DELAY:
    MOV TH0,#0F9H

    SETB TR0
    HERE: JNB TF0,HERE
    CLR TF0

      DELAY:H2:MOV R0,#12H;
      H1: MOV R1,#0F7H;
      MOV R2,# 0FFH;
      AGAIN : DJNZ R2, AGAIN;
      DJNZ R1, H1;
      DJNZ R0,H2;
      RET;
