Note:
1. Represents one standard deviation from the mean.
2. The factory-calibrated offset value is stored in the read-only area of flash in locations 0xFFD4 (low byte) and 0xFFD5 (high byte).
The 14-bit result represents the output of the ADC when sampling the temp sensor using the 1.65 V internal voltage reference.
3. Temp sensor error is based upon characterization and is not tested across temperature in production. The values represent three
standard deviations above and below the mean.
