Register Name Description
0x87 Read [6:0] New Data Flags
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.
Bit Data Packet Changed
0 AVI infoframe.
1 audio infoframe.
2 SPD infoframe.
3 MPEG source infoframe.
4 ACP packets.
5 ISRC1 packets.
6 ISRC2 packets.
0x88 Read [7:0] Active Line Start MSB Active line start MSB (see Register 0x86).
0x89 Read [7:0] Active Line End LSB
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.
0x8A Read [7:0] Active Line End MSB Active line end MSB. See Register 0x89.
0x8B Read [7:0] Active Pixel Start LSB
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.
0x8C Read [7:0] Active Pixel Start MSB Active pixel start MSB. See Register 0x8B.
0x8D Read [7:0] Active Pixel End LSB
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.
0x8E Read [7:0] Active Pixel End MSB Active pixel end MSB. See Register 0x8D.
0x8F Read [6:0] New Data Flags New data flags (see 0x87).
