CM16t18
Command Mapping From 16-bit to 18-bit or 8-bit to 9-bit Data Bus
Used for 18-bit/9-bit RGB666 MPU-Interfaced LCD device mode.
0 = For 18-bit data bus mode,.
Data[17:0] = {Command[15:8], 1’b0, Command[7:0],. 1’b0};
For 9-bit data bus mode,
Data[8:0] = {Command[7:0],.
1’b0};
1 = For 18-bit data bus mode,.
Data[17:0] = {2’b00, Command[...15:0]};
For 9-bit data bus mode,
Data[8:0] = {1’b0, Command.[7:0]};
