7.26.3
PCMx Overflow (Read Only)
Indicates the over-range status in the PCM data path.
7.27
Battery Compensation (Address 2Fh)
7.27.1
Battery Compensation
Configures automatic adjustment of the speaker volume when VP deviates from VPREF[3:0].
7.27.2
VP Monitor
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, re-
gardless of the VPMONITOR setting. Conversely, when BATTCMP is disabled, the ADC may be en-
abled by enabling VPMONITOR; this provides a convenient battery monitor without enabling battery
compensation.
2.
When enabled, VPMONITOR remains enabled regardless of the PDN bit setting.
PCMxOVFL
PCM Overflow Status:
0
No digital clipping has occurred in the data path of the PCM (“PCM Channel x Volume” on page 47) of the
DSP.
