PRELIMINARY DATA SHEET
3.3.2.3. STANDARD RESULT Register
If Automatic Standard Detection is selected in the
STANDARD SELECT register, status and result of the
Automatic Standard Detection process can be read out
of the STANDARD RESULT register. The possible
results are based on the mentioned Standard Code
and are listed in Table 3–8.
In cases where no sound standard has been detected
(no standard present, too much noise, strong interfer-
ers, etc.) the STANDARD RESULT register contains
00 00
actions (for example, set the standard according to a
preference list or by manual input).
As long as the STANDARD RESULT register contains
a value greater than 07 FF
Detection is still active. During this period, the MODUS
and STANDARD SELECT register must not be written.
The STATUS register will be updated when the Auto-
matic Standard Detection has finished.
If a present sound standard is impossible for a specific
MSP version, it detects and switches to the analog
mono sound of this standard.
Example:
The MSPs 3431G and 3441G will detect a B/G-NICAM
signal as standard 3 and will switch to the analog FM-
Mono sound.
