Detects a TMDS DE.
Detects a TMDS clock.
Tells the Macrovision detection engine to enter PAL mode.
Sets the start line for Macrovision detection.
Description
Gives the status of AV mute based on general control packets.
Returns 1 when read of EEPROM keys is successful.
Returns quality number based on DE edges.
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 because it can change on a frame by frame basis.
Returns DVI HSYNC polarity.
Returns DVI VSYNC polarity.
Returns current HDMI pixel repetition amount. 0 = 1×, 1 = 2×, ...
The clock and data outputs automatically decimate by this value
to present the data in the original form.
Sets the maximum pseudo sync pulse width for Macrovision
detection.
Sets the minimum pseudo sync pulse width for Macrovision
detection.
Tells the Macrovision detection engine whether we are
oversampling or not.
0 = standard definition.
1 = progressive scan mode.
0 = use hard-coded settings for line counts and pulse widths.
1 = use I
Sets the end line for Macrovision detection.
Sets the number of pulses required in the last 3 lines (SD mode
only).
Sets audio PLL to low frequency mode. Low frequency mode
should only be set for pixel clocks <80 MHz.
Allows the previous bit to be used to set low frequency mode
rather than the internal auto-detect.
0 = repeat Cr and Cb values.
1 = interpolate Cr and Cb values.
Enables the FIR filter for 4:2:2 CrCb output.
Enables the 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, and C4 offsets.
00 = ±1.0, −4096 to +4095.
01 = ±2.0, −8192 to +8190.
1× = ±4.0, −16384 to +16380.
