Description
The VBMON registers are used to determine the battery voltage. Before entering a low power state, the device will determine the voltage
level by starting at VBMON_RANGE 11 (90% to 100%), and if VBMON_TH of 000 is read, then it will move to VBMON_RANGE 10 (80%
to 90%) and continue until a non 000 value of VBMON_TH is found. If this does not happen, then VBMON_RANGE and VBMON_TH will
be written with 00 000. The VBMON_READ bit can be used to initiate a new reading by writing a 1 to it. Example: A reading of 10 011
indicated a VBAT voltage of between 84% and 86% of the VBATREG setting.
