STATus:QUEStionable:NTR
STATus:QUEStionable:PTR
These commands allow you to set or read the value of the Questionable NTR (Negative-Transition) and
PTR (Positive-Transition) registers. These registers serve as polarity filters between the Questionable
Enable and Questionable Event registers to cause the following actions:
$ When a bit of the Questionable NTR register is set to 1, then a 1-to-0 transition of the corresponding
bit of the Questionable Condition register causes that bit in the Questionable Event register to be set.
$ When a bit of the Questionable PTR register is set to 1, then a 0-to-1 transition of the corresponding
bit in the Questionable Condition register causes that bit in the Questionable Event register to be set.
$ If the same bits in both NTR and PTR registers are set to 1, then any transition of that bit at the
Questionable Condition register sets the corresponding bit in the Questionable Event register.
$ If the same bits in both NTR and PTR registers are set to 0, then no transition of that bit at the
Questionable Condition register can set the corresponding bit in the Questionable Event register.
