Description
HSYNC delay in lower 2 bits (see R0x35).
VSYNC delay in for DE generation.
Sets the difference (in HSYNCs) in field length
between Field 0 and Field 1.
Most significant 5 bits for frame width.
Lower 7 bits for frame width (see R0x37).
Most significant 8 bits for frame height.
Lower 4 bits for frame height (see R0x39).
Audio sampling frequency select.
valid when using SPDIF input
0 = Fs extracted from SPDIF
1 = Fs set via R0x15[7:4]
Default = 1 (only used during pixel repetition mode).
Pixel repetition mode selection. Set to b00 unless
non-standard video is supported.
00 = auto mode.
01 = max mode.
1x = manual mode (see R0x3B Bits [4:3]).
Default = 00.
External value for PLL pixel repetition.
00 = ×1.
01 = ×2.
10 = ×4.
11 = ×4.
Default = 00.
User programmed pixel repetition number to send to
RX. Default = 00.
CSC enable.
0 = no CSC.
1 = enable CSC.
Default = 0.
User programmed VID to send to Rx. See Table 24 for
full VID formats. Default = 0x00.
The actual pixel repetition sent to Rx.
The actual VID sent to HDMI Rx (see Table 24).
VID detected by video FE (see Table 24).
This register is for video input formats that are not
inside the 861B table.
000 = 480i not active.
001 = 240p not active.
010 = 576i not active.
011 = 288p not active.
100 = 480i active.
101 = 240p active.
110 = 576i active.
111 = 288p active.
Default = 000.
Information about 240p and 288p.
240p – 01 = 262 lines.
240p – 10 = 263 lines.
288p – 01 = 312 lines.
288p – 10 = 313 lines.
288p – 11 = 314 lines.
Default = 00.
