Figure 133. Regular oversampling modes (4x ratio)
Oversampling Injected channels only
The Injected oversampling mode bit JOVSE enables oversampling solely for conversions in
the injected sequencer.
Oversampling regular and Injected channels
It is possible to have both ROVSE and JOVSE bits set. In this case, the regular
oversampling mode is forced to resumed mode (ROVSM bit ignored), as represented on
Figure 134 below.
