Input/Output Select Terminal for DATA Terminal
During the CE terminal is "L", the DATA terminal is high impedance.
Quartz Crystal Connecting Terminal (f=32.768kHz)
Refer to the line-up table for internal Cg, Cd value.
Chip Enable Input Terminal (with Pull-down Resistance)
When the CE signal is which rising edge or falling edge,
the CLK signal should be fixed to "L".
Clock Input Terminal
The DATA input/output is synchronized this clock.
When the CE terminal is "L" the DATA terminal is high impedance.
