Power pin
– Connect to GND.
Input When “L”, this pin resets the internal IC circuit. Hysteresis input. Built-in pull-up resistor.
Input
Input
This is the chip select input pin, and when serial data transmission is being carried out, it
goes to “L”. Hysteresis input. Built-in pull-up resistor.
__
When CS pin is “L”, SIN serial data is taken in when SCK rises. Hysteresis input. Built-in
pull-up resistor.
Input This is the pin for serial input of data and addresses for the display control register and
the display data memory. Hysteresis input. Built-in pull-up resistor.
Input This is the pin for external clock input.
– Please connect to +5V with the power pin.
Output This is the output port. Port data is set by PTD6.
Output This is the output port. Port data is set by PTD7.
– Please connect to GND using circuit earthing pin.
Output This pin can be toggled between port pin output and BLNK0 signal output.
Output This pin can be toggled between port pin output and R signal output.
Output This is the output port. Port data is set by PTD2.
Output This pin can be toggled between port pin output and G signal output.
Output This is the output port. Port data is set by PTD4.
Output This pin can be toggled between port pin output and B signal output.
Input This pin inputs the horizontal synchronous signal. Hysteresis input.
Input This pin inputs the vertical synchronous signal. Hysteresis input.
– Please connect to +5V with the power pin.
