Setting the alarm clock
Registers 1FF5h-1FF2h contain the alarm settings. The alarm can be configured to go off at
a prescribed time on a specific day of the month or repeat every month, day, hour, minute, or
second. It can also be programmed to go off while the M48T59/Y/V is in the battery back-up
mode of operation to serve as a system wake-up call.
Bits RPT1-RPT4 put the alarm in the repeat mode of operation. Table 6 on page 16 shows
the possible configurations. Codes not listed in the table default to the once per second
mode to quickly alert the user of an incorrect alarm setting.
Note:
User must transition address (or toggle chip enable) to see Flag Bit change.
When the clock information matches the alarm clock settings based on the match criteria
defined by RPT1-RPT4, AF (Alarm Flag) is set. If AFE (Alarm Flag Enable) is also set, the
