6.7. Demodulator Source Channels in Manual Mode

6.7.1. Terrestric Sound Standards

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.

6.7.2. SAT Sound Standards

Table 6–18 shows the source channel assignment of

the demodulated signals for SAT sound standards.

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

the FM2 channel.

2. FM adaptive deemphasis cannot be processed

simultaneously with FM-identification.

6.9. Compatibility Restrictions to MSP 34x0D

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:

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.
