Table 346 shows which CLD[23:0] pins provide the pixel data to the STN panel for each
mode of operation. The abbreviations used in the table are defined as follows:
– CUSTN = Color upper panel STN, dual and/or single panel
– CLSTN = Color lower panel STN, dual
– MUSTN = Mono upper panel STN, dual and/or single panel
– MLSTN = Mono lower panel STN, dual
