DESCRIPTION
This pin is used to initialize the internal state of the M66004.
"L" : Communication with the MCU is possible.
"H" : Any instruction from the MCU is neglected.
At the rising edge from "L" to "H", input data is shifted.
Character code or command data to display is input from MSB.
This pin is used to connect a resister and a capacitor externally to
set oscillation frequency.
These pins are used to connect to digit pins of VFD.
These pins are used to connect to segment pins of VFD.
Output port (static operation)
Positive power supply for internal logic.
u163
Positive power supply for high-pressure-resistant output port.
.
GND
Negative power supply for VFD drive.
