STAT:OPER:NTR|PTR Commands
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-I 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 value of the PTR or NTR filter can of itself generate positive or negative events in the
corresponding Operation Event register.

Status Questionable Registers
The bit configuration of all Status Questionable registers is as follows:
Bit Configuration of Questionable Registers
Bit Position 15-11 10 9 8 7 6 5 4 3 2 1 0
Condition NU UNR RI NU NU NU NU OT NU NU OC OV
Bit Weight 1024 512 256 128 64 32 16 8 4 2 1
NU = (Not used); OC = Overcurrent protection circuit has tripped; OT = Overtemperature status condition exists;
OV = Overvoltage protection circuit has tripped; RI = Remote inhibit is active; UNR = Power supply output is
unregulated.
Note See "Chapter 4 - Status Reporting" for more explanation of these registers.
