DATA SHEET
6. Appendix B: Manual/Compatibility Mode
To adapt the modes of the STANDARD SELECT regis-
ter to individual requirements and for reasons of com-
patibility to the MSP 34x0D, the MSP 34x0G offers
an Manual/Compatibility Mode, which provides sophis-
ticated programming of the MSP 34x0G.
Using the STANDARD SELECT register generally pro-
vides a more economic way to program the
MSP 34x0G and will result in optimal behavior. There-
fore, it is not recommend to use the Manual/Com-
patibility
MSP 34x0D is to be substituted by the MSP 34x0G,
the tips given in Section 6.9. on page 101 have to be
obeyed by the controller software.

Controlling of MSP-Demodulator and Interface options. As soon as this
register is applied, the MSP 34x0G works in the MSP 34x0D compatibility
mode.
Warning: In this mode, BTSC, EIA-J, and FM-Radio are disabled. Only
MSP 34x0D features are available; the use of MODUS and STATUS register
is not allowed.
The MSP 34x0G is reset to the normal mode by first programming the
MODUS register followed by transmitting a valid standard code to the
STANDARD SELECTION register.
