Functional description
Connect a ground to this pin. (Digital system ground)
Digital system power supply: +3.3V
Connect to the character output dot clock generator oscillator coil and
capacitor.
Receives an external clock signal.
Capacitor coupling, 50% duty cycle, 0.5Vp-p or higher
Switches between external clock input mode and LC oscillator mode.
Low: LC oscillator, high: external clock input MORE+
OR control with MORE+ command
Clock input for the serial data input system
MORE+ (This input has hysteresis characteristics.)
Serial data input
MORE+ (This input has hysteresis characteristics.)
Enable input for the serial data input system. Serial data input is enabled
when this pin is set low.
