Notes: 1. "x" in the FRQCR setting depends on the setting in bits 12, 13, and 15.
2. The ratio of clock frequencies, where the input clock frequency is assumed to be 1.
3. These values are the clock frequencies of the EXTAL pin input or a crystal resonator in modes 0
and 2.
In modes 1 and 3, these values are the clock frequencies of the USB_X1 pin input or a crystal
resonator.
