Figure 107. Regular and injected oversampling modes used simultaneously
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 108 below.
Figure 108. Triggered regular oversampling with injection
Autoinjected mode
It is possible to oversample auto-injected sequences and have all conversions results stored
in registers to save a DMA resource. This mode is available only with both regular and
injected oversampling active: JAUTO = 1, ROVSE = 1 and JOVSE = 1, other combinations
are not supported. The ROVSM bit is ignored in auto-injected mode. The Figure 109 below
shows how the conversions are sequenced.
