Note 1: The PLL accepts a 1.97 MHz to 4.04 MHz input frequency. Higher input frequencies, up to 48 MHz, may be
supplied to the PLL if they are prescaled down by the PLLDIVx Configuration bits into the 1.97 MHz to
4.04 MHz range.

Note 1: To achieve this accuracy, physical stress applied to the microcontroller package (ex., by flexing the PCB)
must be kept to a minimum.
2: Accuracy measured with respect to reference source accuracy.
3: Time from reference clock is stable and in range until the FRC is tuned within the range specified by F20
(with self-tune).
4: Other frequencies that are derived from the FRC (either through digital division by prescalers or multiplication
through a PLL) will also have the same accuracy tolerance specifications as provided here.
