PIN NAME DESCRIPTION
Reset input This pin is used to initialize the internal state of the M66004.
"L" : Communication with the MCU is possible.
Chip select input
"H" : Any instruction from the MCU is neglected.
Shift clock input At the rising edge from "L" to "H", input data is shifted.
Serial data input Character code or command data to display is input from MSB.
Clock input This pin is used to connect a resister and a capacitor externally to
Clock output set oscillation frequency.
Digit output These pins are used to connect to digit pins of VFD.
Segment output These pins are used to connect to segment pins of VFD.
