STATus:QUEStionable:ENABle
This command sets or reads the value of the Questionable Enable register. This register is a mask for
enabling specific bits from the Questionable Event register to set the questionable summary (QUES) bit of
the Status Byte register. This bit (bit 3) is the logical OR of all the Questionable Event register bits that are
enabled by the Questionable Status Enable register.

STATus:QUEStionable:NTRansition
STATus:QUEStionable:PTRansition
These commands 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:
u When a bit in the Questionable NTR register is set to 1, then a 1-to-0 transition of the
corresponding bit in the Questionable Condition register causes that bit in the Questionable Event
register to be set.
u 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.
u 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.
u 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.
NOTE: Setting a bit in the PTR or NTR filter can of itself generate positive or negative events in
the corresponding Questionable Event register.
