Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Raster Interrupt Offset
The raster offset value should be set, with
reference to the number of raster lines set in
VDSR.
If the offset value is n, then after horizontal
display interval of the (VDS + n)th raster line, the
RINT bit in DSSR is set to 1 at the falling edge
of HSYNC.
