3.10 3-CHANNEL INDEPENDENT BACKGROUND CONTROL COMMAND
requiring 16 bits for each command, even when continuously input).
This command specifies the background for each of the three output channels (this command is a 2-byte command,
(1) For MSB-first transfer (Command bits are input starting from the MSB (D15).)
(2) For LSB-first transfer (Command bits are input starting from the LSB (D0). The function of each bit is the same as
