Battery Compensation (Address 2Fh)
Notes:
1. The internal ADC that monitors the VP supply is enabled automatically when BATTCMP is enabled, re-
2. When enabled, VPMONITOR remains enabled regardless of the PDN bit setting.
Indicates the over-range status in the PCM data path.
Configures automatic adjustment of the speaker volume when VP deviates from VPREF[3:0].
Configures the internal ADC that monitors the VP voltage level.

abled by enabling VPMONITOR; this provides a convenient battery monitor without enabling battery
compensation.
