3.18. LCM Interfaces
SC66 video output interface (LCM interface) is based on MIPI_DSI standard and supports 8 groups of
high-speed differential data transmission and WQXGA display (resolution: 2560 × 1600), Support dual
display, default DSI+DP (Type-C), optional DSI0+DSI1. Note that DSI1 does not support screens with
command mode.
