Battery Compensation (Address 2Fh)
Indicates the over-range status in the DSP data path.
Indicates the over-range status in the PCM mix data path.
Indicates the over-range status in the ADC signal 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.
Notes:
1. The internal ADC that monitors the VP supply is enabled automatically when BATTCMP is enabled,
2. When enabled, VPMONITOR remains enabled regardless of the PDN bit setting.

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.
