Raghunathan, You can make your interrupt service routine shorter as fellowing: ONESEC: DJNZ COUNT1,EXIT ; 40 interrupts over ? Exit if not MOV COUNT1,#TIME1 ; Yes DJNZ COUNT2,EXIT ; 40 X 100 interrupts over ? Exit if not MOV COUNT2,#TIME2 ; Yes CPL P1.1 ; 1 Sec over. Change output EXIT: RETI Regards, George |
