0x8E—Bits[7:0] Active Pixel End MSB
See Register 0x8D.
0x8F—Bits[6:0] NDF
See Register 0x87.
0x90—Bits[7:0] Audio Infoframe Version
0x91—Bits[7:4] Audio Coding Type
These bits identify the audio coding so that the receiver may
process audio properly.

0x0 Refer to stream header
0x1 IEC60958 PCM
0x2 AC-3
0x3 MPEG1 (Layer 1 and Layer 2)

0x92—Bits[4:2] Sampling Frequency
0x92—Bits[1:0] Ample Size
0x93—Bits[7:0] Max Bit Rate
For compressed audio only, when this value is multiplied by
8 kHz represents the maximum bit rate. A value of 0x08 in this
field yields a maximum bit rate of (8 kHz × 8 kHz = 64 kHz).
0x94—Bits[7:0] Speaker Mapping
These bits define the mapping (suggested placement) of
speakers.
