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

Description
Reserved.
Logic one indicates that the Fault mode has changed according to the configuration of
the ACCMODE register
Logic one indicates that the reactive power sign changed according to the configuration
of ACCMODE register
Logic one indicates that the active power sign changed according to the configuration of
ACCMODE register
Logic one indicates that an interrupt was caused by apparent power no-load detected.
This interrupt is also used to reflect the part entering the IRMS No load mode.
Logic one indicates that an interrupt was caused by reactive power no-load detected.
Logic one indicates that an interrupt was caused by active power no-load detected.
Description
Logic one indicates that a pulse on CF2 has been issued. The flag is set even if CF2 pulse
output is not enabled by clearing bit 2 of MODE1 register.
Logic one indicates that a pulse on CF1 has been issued. The flag is set even if CF1 pulse
output is not enabled by clearing bit 1 of MODE1 register.
Logic one indicates that the VAHR register has overflowded
Logic one indicates that the VARHR register has overflowded
Logic one indicates that the WATTHR register has overflowded
Logic one indicates that the VAHR register is half full
Logic one indicates that the VARHR register is half full
Logic one indicates that the WATTHR register is half full
Description
Indicates the end of a reset (for both sofware or hardware reset).
Reserved
Logic one indicates that new data is present in the Waveform Registers
Logic one indicates that current channel has exceeded the IPKLVL value
Logic one indicates that voltage channel has exceeded the VPKLVL value.
These bits should be kept cleared for proper operation
These bits define the current channel used for energy measurements
[1:0]
00 Current channel automatically selected by the tampering condition
01 Current channel connected to I
10 Current channel connected to I
11 Current channel automatically selected by the tampering condition
Logic one short voltage channel to ground
Logic one short Current channels to ground
