Sets On/Off of field-recursive (3-dimension) noise reduction function.
Although data is written to the memory when the setting is off, all the noise reduction functions are
stopped.
Sets On/Off of noise reduction function demo mode.
Motion compensation stop is the same as YMOFF[3:0] = Fh, CMOFF[4:0] = 1Fh.
