ELECTRONIC CONTRAST CONTROL (32 STEPS)
Electronic Contrast Control data bits is 10h = (C4, C3, C2, C1, C0). Voltage regulation is adjusted as 32-contrast
step according to the value of Electronic Contrast Control data bits. LCD drive voltage V0 has one of 32 voltage
values if 5-bit data is set to the electronic contrast control register (ICONRAM address 10h). When using the
Electronic Contrast Control function, you need to turn the voltage regulators on using power control instruction.
