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.
