0x3D—Bits[7:6] pr_to_Rx

0x43—Bits[7:0] EDID Read Address

This is a programmable I2C address from which the EDID

information (1 to 256 segment) can be read. Default is 0x7E.

0x48—Bits[7:0] Active Line Start LSB

Combined with the MSB in Register 0x49, 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.

0x49—Bits[7:0] Active Line Start MSB

See Register 0x48.

0x4A—Bits[7:0] Active Line End LSB

Combined with the MSB in Register 0x4B, the 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.

0x4B—Bits[7:0] Active Line End MSB

See Register 0x4A.

0x4C—Bits[7:0] Active Pixel Start LSB

Combined with the MSB in Register 0x4D, these bits indicate

the first pixel in the display that is active video. All pixels before

this comprise a left vertical bar. If the 2-byte value is 0x00, there

is no left bar.

0x4D—Bits[7:0] Active Pixel Start MSB

See Register 0x4C.

0x4E—Bits[7:0] Active Pixel End LSB

Combined with the MSB in Register 0x4F, 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.

0x4F—Bits[7:0] Active Pixel End MSB

See Register 0x4E.
