Description
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.

Active line start MSB (see Register 0x86).
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.
Active pixel start MSB. See Register 0x8B.
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.
