In the display RTC routine i am checking for the Alarm

PASS:	inc r1
	mov a,#0C7h
	acall command
	mov a,@r1
	mov 51h,@r1
	mov alarm_chk_min,@r1
	acall disp_val
PASS1:	inc r1
	mov a,#0c4h
	acall command
	mov a,@r1
	mov 52h,@r1
	mov alarm_chk_hour,@r1
	mov r4,a

here i am moving the current time to alarm_chk_hour and min registers so that i can use them while comparing.
