6. Appendix B: Manual Mode
6.1. Demodulator Write and Read Registers for
Manual Mode
To adapt the modes of the STANDARD SELECT regis-
ter to individual requirements, the MSP 44x8G offers a
Manual Mode, which provides sophisticated program-
ming of the MSP 44x8G.
In case of Automatic Sound Select (MODUS[0]=1),
any modifications of all DCO registers listed in
Table 6–1 are ignored.
The Manual Mode can be used only in those cases,
where user specific requirements concerning detec-
tion, identification, or carrier positioning have to be
met.
After the setting of the STANDARD SELECT register,
the MSP 44x8G is set up for optimal behavior. There-
fore, it is not recommended to use the Manual
mode.
