1. Values based on characterization data.
2. After software offset compensation, using the polarity switching (CADPOL) feature.
3. Value includes drift over the whole temperature range.
Clock characteristics
1. The frequency is stored in the Value after factory calibration at 85°C.
2. Value not tested in production, but is guaranteed by design and characterization over the whole temperature range.
3. The actual oscillator frequency is measured in production and store in the device signature row (for detailes, see
