The RW1068 Series can be connected to 6800 Series MPUs. Moreover, using the serial interface it is possible to
operate the RW1068 series chips with fewer signal lines.
The display area can be enlarged by using multiple RW1068 Series chips. When this is done, the chip select
signal can be used to select the individual Ics to access.
