RAM Write Data Mask (R23h)
RAM Write Data Mask (R24h)
WM17–0:
Write-mask the data when these data are written to GRAM by bit. For example, if WM17 = 1,
the WM17 write-mask the MSB of the data to write to GRAM so that the data in the MSB are not written to
GRAM. The rest of WM16-0 bits also write-mask the data in the corresponding bits when these bits are set
to “1”. For details, see the “Graphics Operation Function” section.
The WM17-0 bits write-mask the data to write to GRAM, which are expanded, if necessary, into 18 bits.
This function is not available in the RGB-I/F mode.
