WRITE-DATA MASK FUNCTION
The S6D0114 has a bit-wise write-data mask function that controls writing the two-byte data from the microcomputer
to the GRAM. Bits that are 0 in the write-data mask register (WM17–0) 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
maintained. This function can be used when only one-pixel data is rewritten or the particular display color is
selectively rewritten.
