3.4 ANALOG/DIGITAL CHANNEL MAPPING
Analog channel to digital channel mapping:
The 6 analog ADC channels can be flexibly mapped to the 6 digital
metering/measuring channels (V/I phase A/B/C). Refer to the Channel-
MapI and ChannelMapU registers for configuration.
Note that channel mapping is only valid in Normal mode and Patial
Measurement mode.
