DATA SHEET  
MSP 34x0G  
6.7. Demodulator Source Channels in Manual Mode  
6.7.1. Terrestric Sound Standards  
6.8. Exclusions of Audio Baseband Features  
In general, all functions can be switched independently.  
Two exceptions exist:  
Table 6–17 shows the source channel assignment of  
the demodulated signals in case of manual mode for  
all terrestric sound standards. See Table 2–2 for the  
assignment in the Automatic Sound Select mode. In  
manual mode for terrestric sound standards, only two  
demodulator sources are defined.  
1. NICAM cannot be processed simultaneously with  
the FM2 channel.  
2. FM adaptive deemphasis cannot be processed  
simultaneously with FM-identification.  
6.9. Compatibility Restrictions to MSP 34x0D  
6.7.2. SAT Sound Standards  
The MSP 34x0G is fully hardware compatible to the  
MSP 34x0D. However, to substitute a MSP 34x0D by  
the corresponding MSP 34x0G, the controller software  
has to be adapted slightly:  
Table 6–18 shows the source channel assignment of  
the demodulated signals for SAT sound standards.  
1. The register FM-Matrix (00 0Ehex low part) must be  
changed from “no matrix (00hex)” to “sound A mono  
(03hex)” during mono transmission of all TV-sound  
standards (see also Table 6–17).  
2. With the MSP 34x0G, the STANDARD SELECTION  
initializes the FM-deemphasis, which is not the case  
for the MSP 34x0D. So, if STANDARD SELECTION  
is applied, this I2C instruction can be omitted.
