Interface Connection Reference

The ST7920 controller typically uses a 20-pin interface header. Key signals include: DB0-DB7 (8-bit parallel data bus), RS (Register Select), R/W (Read/Write), E (Enable), PSB (Parallel/Serial select), and reset. For serial mode, only 3 wires (CS, SID, SCLK) are required for SPI communication.
