: This register is set to the all bits zero state when the IC is reset by the RST pin.
When RGB No. 1 or RGB No. 2 is selected:
The A17 to 9 output is set to the RD2 to BD0 three-value output. (Supported by connecting external resistors.)
*
It will not be possible to use external ROM in this case. (Only internal ROM can be used.)
No. 1: RGB = 000 = Black only. Here the output will go to the high-impedance state giving the middle level due to the external resistor.
For areas other than the display area, the output will be at the low level.
No. 2: When any individual color is zero, the output will go to the high-impedance state giving the middle level due to the external resistor.
For areas other than the display area, the output will be at the low level.
