(MSR)
This register is used to define the signal source, the level of which is to be monitored, and the signal channel. Data can
be monitored before or behind the DC filter at the FM/AM demodulator outputs. The last available data sample can be
read-out in the I
2
C-bus slave transmitter mode (see Section 7.4.5).
Phase means the differentiated phase output of the FM demodulator and is provided, when the demodulator operates in
FM mode, while magnitude is supplied in AM mode.
The default setting at power-up is 00000000.
