VBat
The VBat register contains the measured battery voltage in mV. For example, 2970 represents 2.970 volts.
This value is periodically updated by the internal IF-006 firmware.
7.5.2
Vdc
The Vdc register contains the measured USB/External voltage in mV. For example, 4770 represents 4.770
volts. This value is periodically updated by the internal IF-006 firmware.
