–
Connect to GND.
Input When “L”, this pin resets the internal IC circuit. Hysteresis input. Built-in pull-up resistor.
Input
<At 24-bit serial communication>
This is the pin for chip select. Set to “L” level at serial data transmission. Hysteresis input.
Built-in pull-up resistor.
<At I²C-BUS communication>
Connect to “H.”
Input
<At 24-bit serial communication>
__
SIN pin serial data is taken in when SCK rises at CS pin “L” level.
Hysteresis input.
<At I²C-BUS communication>
SDA pin serial data is taken in when SCL rises.
Input
<At 24-bit serial communication>
This is the pin for serial input of display control register and display RAM data. Hysteresis
input.
I/O <At I²C-BUS communication>
Hysteresis input. This is the pin for serial input of display control register and display
RAM data. Also, this pin output acknowledge signal.
Input This is the pin for external clock input.
