This instruction is for writing data from the microcomputer to the internal GRAM of HD66781.
ODF: Set the format to write OSD data to the internal RAM. When ODF =0, assign transmission rate bits
(α channel) to the LSB of RGB data. When ODF = 1, assign transmission rate bit (α channel) to the MSB.
OSD bit must be “1” when writing OSD data.
