These commands set or read the value of the Operation NTR (Negative-Transition) and PTR (Positive-
Transition) registers. These registers serve as polarity filters between the Operation Enable and
Operation Event registers to cause the following actions:
u When a bit in the Operation NTR register is set to 1, then a 1-to-0 transition of the corresponding bit

in the Operation Condition register causes that bit in the Operation Event register to be set.

u When a bit of the Operation PTR register is set to 1, then a 0-to-1 transition of the corresponding bit

in the Operation Condition register causes that bit in the Operation Event register to be set.

u 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.

u 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.

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.
