Description
Reserved. Set to 1.
Display Enable Skew Control. This value is a binary encoded value that specifies how
many character clocks to skew the horizontal display enable signal by (0 character clocks
- 3 character clocks) before it is sent to the attribute controller. This field is used to
accommodate differences in the length of the video pipeline (frame buffer to pixel output)
in various text and graphics modes.
Horizontal Blank End Register Bits [4:0]. This 6-bit value is a compare target for the
character count where the horizontal blank signal ends. Bit 5 of this value is in the Hori-
zontal Sync End register (Index 05h[7]). Note that not all horizontal counter bits are com-
pared, which can create aliased compares depending upon the binary values involved in
the count range and compare values.
Description
Horizontal Sync Start. This value specifies the character position where the horizontal
sync pulse starts.

Not Implemented. (HSync Delay).
Horizontal Sync End. These bits represent the low five bits of the character position
where the horizontal sync signal ends.
