Display off output registers H and L (DOORH, DOORL) are 16-bit readable/writable registers that
specify the display data to be output from pins DD0 to DD17 when DRES = 0 and DEN = 1.
A6-bit setting is made for each of the RGB components, in bits DOR, DOG, and DOB.

be written to these bits.
DOORH/L bits DOR, DOG, and DOB retain their values in a reset.
