1.2.3 Calibrated 32 MHz RC Oscillator

This RC oscillator provides an approximate 32 MHz clock. The oscillator employs a DFLL that can be enabled for automatic run-time calibration of the oscillator. A factory-calibrated value is written to the 32 MHz DFLL Calibration register during reset to ensure that the oscillator is running within its specification. The Calibration register can also be written from software for manual run-time calibration of the oscillator.
