When "L", M66005 is initialized.
When "L", communication with the MCU is possible.
When "H", any instruction from the MCU is neglected.
Shift clock input
Serial input data is taken and shifted by the positive edge of SCK.

Clock input
Clock output
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.
DIG00~
DIG15
Digit output
Connect to digit (grid) pins of VFD.
Connect to segment (anode) pins of VFD. Pins from SEG00 to
SEG39 correspond to segment pins of VFD as shown in the table
below. SEG36~SEG39 pins are common to DIG12~DIG15 pins.
So, when use SEG36~SEG39, the number of digit to be used is
decreased.
Segment output
Universal port
Generally, use this port as the static output port.
This port also operates as the timing IN/OUT port to control
another M66005.
Positive power supply for internal logic.
Positive power supply for DIG and SEG outputs.
GND (0V)
Negative power supply to pull down.

P1 : bidirectional
P0 : output
