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.
