NF Frame Noise Update Enable
0: Do not Update
1: Update
When set to 1, frameNoise_previous registers get updated at the
end of current frame processing. When set to 0.. updates are not
done allowing next frame to use the same initial frame noise value
used by the previous frame.

NF Frame Noise Load Enable
When a new video is assigned to nf_video_index.. this bit needs to
be set to initialize (clear or reload) internally stored
frameNoise_previous registers.
0: Do not overwrite
1: Inititalize (overwrite)
When set to 1, values last written into NF_REG8 and NF_REG9 are
