This gain is not recommended in the ADE7166 and ADE7169 because it can create an overranging of the ADC when both current inputs are in opposite phase.
This register is not available in the ADE7566 and ADE7569.

Description
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.
Reserved.
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 detected. This interrupt is also
used to reflect the part entering the I
Logic 1 indicates that an interrupt has been caused by reactive power no-load detected.
Logic 1 indicates that an interrupt has been caused by active power no-load detected.
Description
Logic 1 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 the MODE1 register.
Logic 1 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 the MODE1 register.
Logic 1 indicates that the VAHR register has overflowed.
Logic 1 indicates that the VARHR register has overflowed.
Logic 1 indicates that the WATTHR register has overflowed.
Logic 1 indicates that the VAHR register is half full.
Logic 1 indicates that the VARHR register is half full.
Logic 1 indicates that the WATTHR register is half full.
These bits define the current channel input gain.
