WEMODE=1: When the transfer number of data exceeds (EC-SC+1)*(EP-SP+1), the column and page number will be reset, and the exceeding data will be written into the following column and page. ENDIAN: Select Little Endian Interface bit. At Little Endian mode, the host sends LSB data first. DM [1:0]: Select the display operation mode. RM: Select the interface to access the GRAM. RIM: Specify the RGB interface mode when the RGB interface is used. These bits should be set before display operation through the RGB interface and should not be set during operation. EPF [1:0]: 65K color mode data format.
