Description
Noise measurement algorithm
1: measurement during vertical blanking period (measure
line can be defined by NMLINE)
0: measurement in the first active line
Line for noise measurement (only valid for NMALG=1)

Description
Noise level of the input signal: 0 (no noise), ... , 30
(strong noise) [31 (strong noise or measurement failed)]
Signals a new value for NOISEME
1: a new value can be read
0: current noise measurement not finalized
