1 _{Typical data was characterized at 3.0 V, 25°C or is recommended value.}
2 _{When MCG is configured for FEE or FBE mode, the input clock source must be divisible using RDIV to within the range of}
31.25 kHz to 39.0625 kHz.
3 _{When MCG is configured for PEE or PBE mode, input clock source must be divisible using RDIV to within the range of 1 MHz}
to 2 MHz.
4 _{This parameter is characterized and not tested on each device. Proper PC board layout procedures must be followed to}
achieve specifications. This data will vary based upon the crystal manufacturer and board design. The crystal should be
characterized by the crystal manufacturer.
5 _{4 MHz crystal.}
