(Forwarding connection of segment output terminal.)
M66005FP Terminal Function
Initialzes internal state of M66005.
Able to communicate with MCU in "L" mode.
Command from MCU will be disregareded in "H" mode.
Shifts input data at rise from "L" to "H".
Inputs character code or command data needed to display from MSB.
Sets oscillation frquency by connecting external resistor and capacitor (maximum
oscillation frequency fosc (max)=1MHz). Also feasible to apply external clock. In this case,
inject external clock to Xin terminal and open Xout terminal.
Connect to digit terminal of VFD. DIG00~DIG15 correspond to the 1st figure to 16th figure
respectively.
Connect to segment terminal of VFD. For corresponding SEG00~SEG35 to segment
terminal of VFD, refer to the figure right.
Output port (static operation).
Positive power supply terminal for internal logic.
Positive power supply terminal for high tension output port.
GND terminal.
Negative power supply terminal for VFD drive.
in the right figure indicates 1 dot of segment, the figure in shows the segment output
terminal number (00~35) to be connected.
