Figure 12-24. PSCn behavior versus PSCn Input A in Fault Mode 2
PSC Input A is take into account during DT0 and OT0 only. It has no effect during DT1 and OT1.
When PSCn Input A event occurs, PSC releases PSCOUTn0, jumps and executes DT1 plus OT1 and then
waits for PSC Input A inactive state.
Even if PSC Input A is released during DT1 or OT1, DT1 plus OT1 sub-cycle is always completely
executed.
Figure 12-25. PSCn behavior versus PSCn Input B in Fault Mode 2
PSC Input B is take into account during DT1 and OT1 only. It has no effect during DT0 and OT0.
When PSC Input B event occurs, PSC releases PSCOUTn1, jumps and executes DT0 plus OT0 and then
waits for PSC Input B inactive state.
Even if PSC Input B is released during DT0 or OT0, DT0 plus OT0 sub-cycle is always completely
executed.
