18.6 Alarm Function
One of the following three signals is output to the ALARM pin.
(1) “0” pulse (when the alarm register corresponds with the clock)
(2) 1Hz cycle “0” pulse
(3) 16Hz cycle “0” pulse
the INTRTC interrupt request simultaneously.
state in the CG Interrupt Mode Control Register.
(1) “0” pulse (when the alarm register corresponds with the clock)
(Note)
By writing “1” to RTCPAGER<PAGE>, the alarm function of the PAGE1 registers is enabled.
In any cases shown above, the INTRTC outputs one cycle pulse of low-speed clock. It outputs
The INTRTC interrupt signal is falling edge triggered. Specify the falling edge as the active

triggered.

operating at high frequency oscillation, a maximum of one clock delay at 32 kHz (about 30µs)
may occur for the time register setting to become valid.
“0” pulse is output to the ALARM pin when the values of the PAGE0 clock register and the

Setting alarm for min., hour, date and day is done by writing data to the relevant PAGE1
The following is an example program for outputting an alarm from the ALARM pin at noon
The above alarm works in synchronization with the low-speed clock. When the CPU is

To make the alarm work repeatedly (e.g. every Wednesday at 12:00), next alarm
must be set during the INTRTC interrupt routine that is generated when the time
set for the alarm matches the RTC count.
