PRODUCTION DATA
A 10-bit SAR ADC monitors VBAT voltage VBAT_CNV, PVDD voltage PVDD_CNV and die temperature TMP_CNV. VBAT voltage conversions are also used by the limiter and brown out prevention features.
Actual VBAT voltage is calculated by dividing the VBAT_CNV register by 64. Actual die temperature is calculated by subtracting 93 from TMP_CNV register. The battery voltage VBAT can be filtered using VBAT_FLT register but will increase the latency. The VBAT_CNV registers should be read VBAT_MSB followed by VBAT_LSB.
