Explanation of the Alarm Function
from
when the falling edge is detected. RTC is not initializes by RESET. Therefore, when clock or
alarm function is used, clear interrupt request flag in INTC (interrupt controller).
(1) In accordance of alarm register and a timer, output 0.
Note: This set up time is unnecessary when you use only internal interruption.
(2) When output clock of 1 Hz
(3) When output clock of 16 Hz
Can use alarm function by setting of register of PAGE1 and output either of three signal

clock at 32 kHz (about 30 µs) for the time register setting to become valid. In the above
example, it is necessary to set 31 µs of set up time between setting the time register
and enabling the alarm register.
RESTR<DIS1HZ> = 0, <DIS16HZ> = 1. And RTC generates INTRTC interrupt by
falling edge of the clock.
RESTR<DIS1HZ> = 1, <DIS16HZ> = 0. And RTC generates INTRTC interrupt by
falling edge of the clock.
(1) In accordance of alarm register and the timer, output “0”.
(2) Output clock of 1 Hz.
(3) Output clock of 16 Hz.
