Forum -> Project Addition or Changes
actually you did not edited the code properly.
you removed many things which were necessary for the clock. I am giving you one example...
In your code above there is a mistake..
CODE:
done:
mov sec,#00h ;For more information about the RTC DS1307
mov min,#0h ;Please refer to the datasheet
mov hour,#51h ;21h for 24 hour format
mov days,#01h
mov date,#1h
mov month,#1h
mov year,#05h

HOW TO SET 5 DIFFERNET ALARMS IN THE DIGITAL CLOCK PGM
Forum -> Project Addition or Changes
setting alarm, this is just an example...

eg you create two variables, alarm_hr and alarm_min
alarm_hr will have the address where hr of the alarm is going to be stored and alarm_min will have the address where min of the alarm is going to be stored, so before calling the alarm set routine, you fill these variables with the addresses, where you want to store the alram.
say...
for alarm 1: hr is store...[more]
24h   variables   alarm time   time is going   mov
