Configuring Oversampling DI operating mode

Oversampling DI
The Oversampling DI function detects 32 signal states of a given digital input at equal
intervals per application cycle (for example OB 91, OB 6x). The 32 states are returned
together as a 32-bit value in the feedback interface. The value is read in synchronously to Ti
(actual value acquisition).
Note
Isochronous mode
Oversampling requires isochronous mode.
