Operation Status Group
The Operation Status registers record signals that occur during normal operation. As shown below, the
group consists of a Condition, PTR/NTR, Event, and Enable register. The outputs of the Operation Status
register group are logically-ORed into the OPERation summary bit (7) of the Status Byte register.

Command Description
A register that holds real-time status of the circuits
being monitored. It is a read-only register.
A positive transition filter that functions as described
under STAT:OPER:NTR|PTR commands in chapter 6.
It is a read/write register.
A negative transition filter that functions as described
under STAT:OPER:NTR|PTR commands in chapter 6.
It is a read/write register.
A register that latches any condition that is passed
through the PTR or NTR filters. It is a read-only
register that is cleared when read.
A register that functions as a mask for enabling specific
bits from the Event register. It is a read/write register.
