1. Clock control unit
Generates the chip-enable signals (EIO1, EIO2) and controls internal timing signals.
2. Data inversion circuit
Uses the POL1 and POL2 signals to perform polarity inversion (at high levels) or non-inversion (at
low levels) processing of input display data.
3. Latch address selector
Generates latch signals for sequentially latching the input display data.
