Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Plane n Memory Length Y
The memory length (Y-direction memory area)
for plane n should be set in raster line units.
When the display exceeds this area, the display
data becomes the data for BPOR.
When the setting is 0, the area is handled as an
infinite area, and so the display data is never the
background color register data.
