Description
This bit is set if any of the ADE status flags that are enabled to generate an ADE interrupt is set. This bit is
automatically cleared when all of the enabled ADE status flags are cleared.

Logic 1 indicates that the fault mode has changed according to the configuration of the ACCMODE register.
Logic 1 indicates that the reactive power sign has changed according to the configuration of the ACCMODE
register.
Logic 1 indicates that the active power sign has changed according to the configuration of the ACCMODE register.
Logic 1 indicates that an interrupt has been caused by apparent power no load detection. This interrupt is
also used to reflect that the part is entering the I rms no load mode.
Logic 1 indicates that an interrupt has been caused by reactive power no load detection.
Logic 1 indicates that an interrupt has been caused by active power no load detection.
