5.2.6.2.2 LINE_SUPPLY_MODE
E981.07
The LINE_SUPPLY_MODE command is used to configure the satellite voltage of each channel and the
frequency of the external oscillator.
Satellite voltages VSAT_OUT of 6.5V or 8.0V can be adjusted. The default voltage is 6.5V. If a satellite voltage
of 8V is requested the satellite voltage bit for the channel must be set.
For every channel the SVx bit influences some DC parameters in table Fehler: Referenz nicht gefunden and
some AC parameters in table 4.2.1.
An external frequency of 4MHz or 8MHz can be adjusted. The default frequency is 4MHz. If an external
frequency of 8MHz is requested the frequency select bit must be set.
