Note: The internal ADC that monitors the VP supply is enabled automatically when BATTCMP is en-
abled, regardless of the VPMONITOR setting. Conversely, when BATTCMP is disabled, the ADC may be
enabled by enabling VPMONITOR; this provides a convenient battery monitor without enabling battery
compensation.
