Pixel Repeat
This value indicates how many times the pixel was
repeated. 0x0 = no repeats, sent once, 0x8 = 8 repeats,
sent 9 times, and so on.
0x86

Active Line Start LSB
Combined with the MSB in Register 0x88, these bits
indicate the beginning line of active video. All lines
before this comprise a top horizontal bar. This is used
in letter box modes. If the 2-byte value is 0x00, there is
no horizontal bar.

New Data Flags (NDF)
This register indicates whether data in specific
sections has changed. In the address space from 0x80
to 0xFF, each register address ending in 0b111 (for
example, 0x87, 0x8F, 0x97, 0xAF) is an NDF register.
They all have the same data and all are reset upon
reading any one of them.

Active Line End LSB
Combined with the MSB in Register 0x8A these bits
indicate the last line of active video. All lines past this
comprise a lower horizontal bar. This is used in letter-
box modes. If the 2-byte value is greater than the
number of lines in the display, there is no lower
horizontal bar.

Active Pixel Start LSB
Combined with the MSB in Register 0x8C, these bits
indicate the first pixel in the display which is active
video. All pixels before this comprise a left vertical bar.
If the 2-byte value is 0x00, there is no left bar.
