Write-data Mask Function
The HD66766R has a bit-wise write-data mask function that controls writing the 16-bit data from the
microcomputer to the GRAM. Bits that are “0” in the write-data mask register (WM15–0) cause the
corresponding DB bit to be written to the GRAM. Bits that are “1” prevent writing to the corresponding
GRAM bit to the GRAM; the data in the GRAM is retained. This function can be used when only one-
pixel data is rewritten or the particular display color is selectively rewritten.
