Communication Protocol
This LCD uses a 4-wire SPI communication interface. SPI communication controls data transmission timing through the combination of clock phase (CPHA) and clock polarity (CPOL). This module uses SPI Mode 0: CPOL = 0 (idle low), CPHA = 0 (sampled on the first edge), with the most significant bit first and the least significant bit last.
