(3) Timer clock setting

When using the real-time clock (RTC) circuit in the device, connect the crystal oscillator of 32.768kHz ±

100ppm to the CCKI and CCKO pins. When using the external RTC circuit, set the CCKI pin to the low level.

See the Port setting for the RTC internal/external selection.

(4) IF signal input

This device's IF signal supports only 1.023MHz. When the signal which is not binary-converted is input, the

signal should go through the DC cut capacitor.

(5) Serial input/output communication system

See the corresponding data sheet for communication because the communication specification differs according

to the communication format. See the Port setting for the communication format selection.

The transmission data (TXD0 and TXD1) amplitude is 0.4V or less for the low level and VDD – 0.4V or more for

the high level. When the LSI and others connected to this operate at 5V and the CMOS level input is used,

convert 3V to 5V for input.
