STATus:OPERation:NTR STATus:OPERation:PTR
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:
• 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.
• 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.
• 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.
