Input Mode Operation
Figure 14-11. PSC Input Filterring
One can select the active edge (edge modes) or the active level (level modes) See PELEVnx
bit description in Section "PSC Module n Input Control Register – PMICn", page 155.
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
Thanks to 4 configuration bits (PRFM3:0), it’s possible to define the mode of the PSC inputs.
Table 14-5.
Notice: All following examples are given with rising edge or high level active inputs.

• In 2- or 4-ramp mode, PSCn Input A is taken into account only during Dead-Time0 and
• In 1-ramp-mode PSC Input A or PSC Input B act on the whole ramp.
