Description
11 = 12-bit 4:2:2 (HDMI can have 12-bit 4:2:2 data).
Enables primary output.
Enables secondary output (DDR 4:2:2 in Output Modes 1 and 2).
Three-state the outputs.
Three-state the SOG output.
Three-state the SPDIF output.
Three-state the I2S output and the MCLK out.
Sets polarity of power-down pin.
0 = active low.
1 = active high.
Selects the function of the power-down pin.
00 = power-down.
01 = power-down and three-state SOG.
10 = three-state outputs only.
11 = three-state outputs and SOG.
0 = normal.
1 = power-down.
0 = disable auto low power state.
1 = enable auto low power state.
Sets the LSB of the address of the HDCP I
second receiver in a dual-link configuration.
0 = Use internally generated MCLK.
1 = Use external MCLK input.
If an external MCLK is used then it must be locked to the video
clock according to the CTS and N available in the I
match between the internal MCLK and the input MCLK results in
dropped or repeated audio samples.
Enables EAV/SAV codes to be inserted into the video output
data.
Allows use of the internal DE generator in DVI mode.
Sets the difference (in Hsyncs) in field length between Field 0
and Field 1.
Sets the delay (in lines) from Vsync leading edge to the start of
active video.
MSB, Register 0x29.
Sets the delay (in pixels) from Hsync leading edge to the start of
active video.
MSB, Register 0x2B.
Sets the width of the active video line (in pixels).
MSB, Register 0x2D.
Sets the height of the active screen (in lines).
Allows Ctrl [3:0] to be output on the I2s data pins.
00 = I2S mode.
01 = right-justified.
10 = left-justified.
11 = raw IEC60958 mode.
Sets the desired bit width for right-justified mode.
