*0******

TMDS Sync Detect

Detects a TMDS DE.

[5]

**0*****

TMDS Active

Detects a TMDS clock.

[4]

***0****

AV Mute

Gives the status of AV mute based on general control packets.

[3]

****0***

HDCP Keys Read

Returns 1 when read of EEPROM keys is successful.

[2:0]

*****000

HDMI Quality

Returns quality number based on DE edges.

0x30

Read

[6]

*0******

HDMI Content

Encrypted

This bit is high when HDCP decryption is in use (content is

protected). The signal goes low when HDCP is not being used.

Customers can use this bit to determine whether or not to allow

copying of the content. The bit should be sampled at regular

intervals since it can change on a frame by frame basis.

[5]

**0*****

DVI Hsync Polarity

Returns DVI Hsync polarity.

[4]

***0****

DVI Vsync Polarity

Returns DVI Vsync polarity.

[3:0]

****0000

HDMI Pixel

Repetition

Returns current HDMI pixel repetition amount. 0 = 1×, 1 = 2×, ...

The clock and data outputs automatically de-repeat by this

value.

0x31

[7:4]

1001****

MV Pulse Max

Sets the max pseudo sync pulse width for Macrovision

detection.

[3:0]

****0110

MV Pulse Min

Sets the min pseudo sync pulse width for Macrovision detection.

0x32

Read/Write

[7]

0*******

MV Oversample En

Tells the Macrovision detection engine whether we are

oversampling or not.

[6]

*0******

MV Pal En

Tells the Macrovision detection engine to enter PAL mode.

[5:0]

**001101

MV Line Count Start

Sets the start line for Macrovision detection.

0x33

Read/Write

[7]

1*******

MV Detect Mode

0 = standard definition.

1 = progressive scan mode.

[6]

*0******

MV Settings Override

0 = use hard coded settings for line counts and pulse widths.

1 = use I2C values for these settings.

[5:0]

**010101

MV Line Count End

Sets the end line for Macrovision detection.

0x34

Read/Write

[7:6]

10******

MV Pulse Limit Set

Sets the number of pulses required in the last 3 lines (SD mode

only).

[5]

**0*****

Low Freq Mode

Sets whether the Audio PLL is in low freq. mode or not. Low

frequency mode should only be set for pixel clocks <80 MHz.

[4]

***0****

Low Freq Override

Allows the previous bit to be used to set low frequency mode

rather than the internal auto-detect.

[3]

****0***

Up Conversion Mode

0 = Repeat Cr and Cb values.

1 = Interpolate Cr and Cb values.

[2]

*****0**

CrCb Filter Enable

Enables the FIR filter for 4:2:2 CrCb output.

[1]

******0*

CSC_Enable

Enables the color space converter (CSC). The default settings for

the CSC provide HDTV to RGB conversion.

Sets the fixed point position of the CSC coefficients. Including

the A4, B4, C4, offsets.

0x35
