Detail of Function
When "L", M66003 is initialized
When "L", communication with the MCU is possible
When "H", any instruction from the MCU is neglected
Serial input data is taken and shifted by the positive edge of SCK
GND (0V)
When use as a CR oscillator, connect external resistor and capacitor / When
use an external clock, input external clock to XIN, and XOUT must be opened
Positive power supply for internal logic
Positive power supply for DIG and SEG outputs
