The HPFs (high-pass filters) in all current channel inputs are disabled when this bit is set.
The LPFs (low-pass filters) in all current channel inputs are disabled when this bit is set.
The frequency output CF is disabled when this bit is set.
By setting these bits, ADE7754’s A/D converters can be turned off. In normal operation, these

Normal operation.
Normal operation. By setting this bit to Logic 1, the analog
inputs to current channel are connected to the ADC for voltage
channel and the analog inputs to voltage channel are connected
to the ADC for current channel.
