Mode Control Register
By writing "1" to RTCPAGER<PAGE>, the alarm function of the PAGE1 registers is enabled. One of the following
In any cases shown above, the INTRTC outputs one cycle pulse of low-speed clock. It outputs the INTRTC interrupt
The INTRTC interrupt signal is falling edge triggered.Specify the falling edge as the active state in the CG Interrupt

to become valid.
"Low" pulse is output to the ALARM pin when the values of the PAGE0 clock register and the PAGE1 alarm
The alarm settings
Initialize the alarm with alarm prohibited. Write "1" to RTCRESTR<RSTALM>.
It makes the alarm setting to be 00 minute, 00 hour, 01 day and Sunday.
Setting alarm for min., hour, date and day is done by writing data to the relevant PAGE1 register.
Enable the alarm with the RTCPAGER <ENAALM> bit. Enable the interrupt with the RTCPAGER <INTE-
The following is an example program for outputting an alarm from the ALARM pin at noon (12:00) on Monday
The above alarm works in synchronization with the low-speed clock. When the CPU is operating at high
