MONITOR SELECT REGISTER (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 e.g. before or after the DC filter at the FM/AM demodulator outputs. The peak level of signals can also be
observed. The last available data sample can be read out in the I2C-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. The magnitude is supplied in AM mode.
The default setting after Power-on reset is 0000 0000.

PEAK
Peak level select: if bit PEAK = 1 it selects the rectied peak level of a source to be
monitored. Peak level value is reset to logic 0 after read-out (see read registers
5 and 6). After changing the monitor signal source for peak calculation it is advisable to
ignore the first read-out value due to stored data from previous calculations.

these bits are not used and should be set to logic 0

MCSM1
Signal channel select: the state of these bits determine which signal channel is
selected; see Table 19.

MSS1
Signal source select: the state of these bits determine which signal source is selected;
see Table 20.
