0x85—Bits[3:0] 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—Bits[7:0] 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.
0x87—Bits[6:0] 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.

0x88—Bits[7:0] Active Line Start MSB
See Register 0x86.
0x89—Bits[7:0] 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.
0x8A—Bits[7:0] Active Line End MSB
See Register 0x89.
0x8B—Bits[7:0] 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.
0x8C—Bits[7:0] Active Pixel Start MSB
See Register 0x8B.
0x8D—Bits[7:0] Active Pixel End LSB
Combined with the MSB in Register 0x8E, these bits indicate
the last active video pixel in the display. All pixels past this
comprise a right vertical bar. If the 2-byte value is greater than
the number of pixels in the display, there is no vertical bar.
