PSC Input A

PSC Input B

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 com-

pletely executed.

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 com-

pletely executed.
