Section 11 Realtime Clock (RTC)
11.5
There are eight kinds of RTC interrupts: a free-running counter overflow, week interrupt, day
interrupt, hour interrupt, minute interrupt, one-second interrupt, 0.5-second interrupt, and 0.25-
second interrupt.
When using an interrupt, set the IENRTC (RTC interrupt request enable) bit in IENR1 to 1 last
after other registers are set.
When an interrupt request of the RTC occurs, the corresponding flag in RTCFLG is set to 1. When
clearing the flag, write 0.

Occurs when the free running counter is
overflowed.
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 one-second
date register is counted.
Occurs every 0.5 seconds.
Occurs every 0.25 seconds.
