The output from the terminal of pin 4 can be changed from clip detector to offset detector output by
sending the write command via I2C.
If the L.P.F output voltage has become a half of pull up voltage for a while, firstly the signal output
volume goes down (cliping detector function). After that, it can be judged that the abnormal output
offset has occurred, if the L.P.F. output voltage does not rise above half of pull up voltage.
