*3 The pins to be connected to the controller (CE, CL, DI, INH) can handle 3.3V or 5V.
*4 Connect the S69/OSCI pin to the LCD panel in the internal oscillator operating mode and insert a current protection
resistor Rg (2.2 to 22kΩ) between the S69/OSCI pin and external clock output pin (external oscillator) in the
external clock operating mode (see “S69/OSCI Pin Peripheral Circuit”).
