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:NTRPTR commands in chapter 8. It is a read/write register.

A negative transition filter that functions as described under STAT:OPER:NTRPTR commands in chapter 8. 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.
