Notes 1. Connect to VDD or VSS according to the selected mode.

2. Input microcontroller output from VDD or VSS according to the selected register.

3. This pin is an output when M,/S = H and CLS = H but should otherwise be used to input the display clock.

4. These pins are pulled down to VSS in the IC.
