1.2.1 Maximum Clock Frequency Limited to 2 MHz for XT Mode
The maximum clock frequency for the intermediate gain setting that supports quartz crystal and ceramic resonator operation (XT mode) is being reduced from 4 MHz to 2 MHz.
Work around
For crystal or resonator frequencies above 2 MHz, use HS mode.
