Data. Data reports power consumption and dissipation of the
IP100A LF at worst-case conditions. To properly interpret the
value read from Data, it must be scaled by the factor indicated in
the DataScale field of the PowerMgmtCtrl register. The value of
Data depends on the value of the DataSelect field of the
PowerMgmtCtrl register.
Data is loaded from the Data field in the EEPROM during a
AutoInit reset.
