Input Mode Operation
If PELEVnx bit set, the significant edge of PSCn Input A or B is rising (edge modes) or the active
level is high (level modes) and vice versa for unset/falling/low
- In 2- or 4-ramp mode, PSCn Input A is taken into account only during Dead-Time0 and On-
Time0 period (respectively Dead-Time1 and On-Time1 for PSCn Input B).
- In 1-ramp-mode PSC Input A or PSC Input B act on the whole ramp.
Thanks to 4 configuration bits (PRFM3:0), it’s possible to define the mode of the PSC input. All
