PSC Input A is taken into account during DT0 and OT0 only. It has no effect during DT1 and
OT1.
When PSC Input A event occurs, PSC releases PSCOUTn0, jumps and executes DT1 plus OT1
plus DT0 while PSC Input A is in active state.
Even if PSC Input A is released during DT1 or OT1, DT1 plus OT1 sub-cycle is always com-
pletely executed.

PSC Input B is taken into account during DT1 and OT1 only. It has no effect during DT0 and
OT0.
When PSC Input B event occurs, PSC releases PSCnOUT1, jumps and executes DT0 plus OT0
plus DT1 while PSC Input B is in active state.
Even if PSC Input B is released during DT0 or OT0, DT0 plus OT0 sub-cycle is always com-
pletely executed.
