Block_Width_UV
Number of UV pixel values which the algorithm uses to generate the noise average.

1 256 pixels (default)
Block_Width_Y
Number of Y pixel values which the algorithm uses to generate the noise average.

Test_Bypass
Test mode bypass. This test bypass mode bypasses the Noise Reduction module completely via hard wires and has zero delay for
processing.
0 Bypass disabled (default)
1 Bypass enabled
NR_Bypass
Noise reduction module bypass. The noise reduction module has a bypass capability which enables it to pass through the incoming
data during the output active video period, while matching the delay in operation mode.
0 Bypass disabled
1 Bypass enabled (default)
