(I

SOSR)
This register is used to define both the signal source to be output at the I
2
S port and the mode of the digital matrix for
signal selection.
The two combinations of FM and NICAM shown in Table 53 apply to the (rare) condition that three different languages
are being broadcast in an FM + NICAM system. They allow for a two-out-of-three selection for special applications. Note
that the controlling microprocessor has to assure that the FM dematrix is set to the mono position.
The default setting at power-up is 00000000.
