Section 10 Realtime Clock (RTC)
10.5
There are five kinds of RTC interrupts: week interrupts, day interrupts, hour interrupts, minute
interrupts, and second interrupts.
When using an interrupt, initiate the RTC last after other registers are set. Do not set multiple
interrupt enable bits in RTCCR2 simultaneously to 1.
When an interrupt request of the RTC occurs, the IRRTA flag in IRR1 is set to 1. When clearing
the flag, write 0.

Occurs when the free running counter is
overflown.
Occurs every week when the day-of-week date
register value becomes 0.
Occurs every day when the day-of-week date
register is counted.
Occurs every hour when the hour date register
is counted.
Occurs every minute when the minute date
register is counted.
Occurs every second when the second date
register is counted.
