ALM0C<2:0>: Alarm 0 Configuration bits
Sets the condition on what the alarm will trigger. The following options are available:
- 000 – Seconds match
- 001 – Minutes match
- 010 – Hours match (logic takes into account 12/24 operation)
- 011 – Day match. Generates interrupt at 12:00:00 AM
- 100 – Date match
- 101 – Unimplemented, do not use
- 110 – Unimplemented, do not use
- 111 – Seconds, Minutes, Hour, Day, Date and Month
bit 3
ALM0IF: Alarm 0 Interrupt Flag bit
This bit is set by hardware when an alarm condition has been generated. The bit must be cleared in
software.
bit 2-0
DAY<2:0>
Note 1:
Contains the BCD day. The range is 1-7. Also, additional bits are used for configuration and status.
