LG2â0: Rewrite data to GRAM after comparing the data that are written by the microcomputer to GRAM

with the values in the compare registers (CP17â0) and performing logical operation. For details, see the

âGraphics Operation Functionâ

CP17â0: Set the value for the compare register, with which the data read out from GRAM or data written

to GRAM by the microcomputer are compared. This function is not available with the external display

interface mode. In the external display interface mode, make sure LG2-0 = â000â.

BGR: Reverse the order from R, G, B to B, G, R to the 18-bit data to write to GRAM. When setting BGR

= 1, CP17-0 and WM17-0 bits will be automatically changed to the same effect.
