These bits always return 0 when read.
Note: These bits are used only when the source data is monochrome.
These 6 bits are used to specify how many bits (up to 63 bits) of monochrome source data
should be skipped over in the first quadword of source data in order to reach the first bit of
valid or desired monochrome source data. These bits are normally used to clip one or more
of the first scanline’s worth of monochrome source data, (i.e. clipping monochrome source
data from the top).
These bits always return 0 when read.
Note: These bits are used only when the source data is monochrome.
These 6 bits are used to specify how many bits (up to 63 bits) of monochrome source data
should be discarded from the end of each scanline’s worth of valid or desired monochrome
source data. These bits are normally used to clip monochrome source data from the right.
These bits always return 0 when read.
Note: These bits are used only when the source data is monochrome.
These 6 bits are used to indicate how many bits (up to 63 bits) of monochrome source data
should be discarded from the beginning of each scanline’s worth of valid or desired
