Product data sheet
8.7.6 Alarm interrupts
Generation of interrupts from the alarm function is controlled via the bit AIE (register
Control_1). If AIE is enabled, the INT1 will follow the status of bit AF (register Control_2).
Clearing AF will immediately clear INT1. No pulse generation is possible for alarm
interrupts.

Example where only the minute alarm is used and no other interrupts are enabled.
