If the same bits in both NTR and PTR registers are set to 1, then any transition of that bit at
the Operation Condition register sets the corresponding bit in the Operation Event register.
If the same bits in both NTR and PTR registers are set to 0, then no transition of that bit at the
Operation Condition register can set the corresponding bit in the Operation Event register.
Note: Setting a bit in the PTR or NTR filter can of itself generate positive or negative events in
the corresponding Operation Event register.

This query returns the value of the Questionable Event register. The Event register is a read-only
register which holds (latches) all events that are passed by the Questionable NTR and/or PTR
filter. Reading the Questionable Event register clears it.
On the Lx\Ls Series, each signal that is fed into the Questionable Status Condition register is
logically-ORed from three corresponding status signals that originate from each phase.
