Notes:

1. Frequency range can be configured in the Supply Controller Registers

2. Not trimmed from factory

3. After Trimming from factory

The 4/8/12 MHz Fast RC oscillator is calibrated in production. This calibration can be read through the Get CALIB
Bit command (see the EEFC section) and the frequency can be trimmed by software through the PMC.
