Connect loop filter to this pin.
Connect to GND.
When “L”, this pin resets the internal IC circuit. Hysteresis input. Built-in pull-up resistor.
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.
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.
This is the pin for external clock input.
Please connect to +5V with the power pin.
This is the output port. Port data is set by PTD6.
This is the output port. Port data is set by PTD7.
Please connect to GND using circuit earthing pin.
This pin can be toggled between port pin output and BLNK0 signal output.
This pin can be toggled between port pin output and R signal output.
This is the output port. Port data is set by PTD2.
This pin can be toggled between port pin output and G signal output.
This is the output port. Port data is set by PTD4.
This pin can be toggled between port pin output and B signal output.
This pin inputs the horizontal synchronous signal. Hysteresis input.
This pin inputs the vertical synchronous signal. Hysteresis input.
Please connect to +5V with the power pin.
