I/O
Reset input
When "L", M66003 is initialized.
Chip select input
When "L", communication with the MCU is possible.
Shift clock input
When "H", any instruction from the MCU is neglected.
Serial data input
Serial input data is taken and shifted by the positive edge of SCK.
GND (0V)
Clock out
When use as a CR oscillator, connect external resistor and capacitor.
Clock in
When use an external clock input external clock to XIN, and XOUT must be opened.
Positive power supply for internal logic.
Segment output
Connect to segment (anode) pins of VFD.
Positive power supply for DIG and SEG outputs.
Segment output
Connect to segment (anode) pins of VFD.
Digital output
Connect to digit (grid) pins of VFD.
Negative power supply to pull down.
