PRELIMINARY DATA SHEET
6.8. Exclusions of Audio Baseband Features
In general, all functions can be switched independently.
Two exceptions exist:
1. NICAM cannot be processed simultaneously with
2. FM adaptive deemphasis cannot be processed
6.9. Phase Relationship of Analog Outputs
The analog output signals: Loudspeaker, headphone,
and SCART2 all have the same phases. The user
does not need to correct output phases when using
these analog outputs directly. The SCART1 output has
opposite phase.
Using the I
ers, care must be taken to adjust for the correct phase.
If the attached coprocessor is one of the MSP family,
the following schematics help to determine the phase
relationship.

6.10. Compatibility Restrictions to MSP 34xxD
The MSP 34x1G is fully hardware compatible to the
MSP 34xxD. However, to substitute a MSP 34xxD by
the corresponding MSP 34x1G, the controller software
has to be adapted slightly:
1. The register FM-Matrix (00 0E
