This represents the line number of the end of the top horizontal
bar. If 0, there is no horizontal bar. Combines with Register 0x88
for a 16 bit value.
New data flags. These 8 bits are updated if any specific data
changes. Normal (no NDFs) is 0x00. When any NDF register is
read, all bits reset to 0x00. All NDF registers contain the same
data.

This represents the line number of the beginning of a lower
horizontal bar. If greater than the number of active video lines,
there is no lower horizontal bar. Combines with Register 0x8A
for a 16-bit value.
Active line end MSB. See Register 0x89.
This represents the last pixel in a vertical pillar-bar at the left side
of the picture. If 0, there is no left bar. Combines with Register
0x8C for a 16-bit value.
This represents the first horizontal pixel in a vertical pillar-bar at
the right side of the picture. If greater than the maximum
number of horizontal pixels, there is no vertical bar. Combines
with Register 0x8E for a16-bit value.
Active pixel end MSB. See Register 0x8D.
