bit 6-4

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.
