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 136

Regular channels
Triggered regular oversampling with injected conversions
It is possible to have triggered regular mode with injected conversions. In this case, the
injected mode oversampling mode must be disabled, and the ROVSM bit is ignored
(resumed mode is forced). The JOVSE bit must be reset. The behavior is represented on
Figure 137
below.
