Notes: 1. With a crystal resonator connected on EXTAL and XTAL, the maximum frequency is 34
MHz. When using a third-order overtone crystal resonator, a tank circuit must be
connected externally.
2. The load capacitance connected on the CLKOUT pin should be not greater than 50 pF.
3. t is the period of one CLKOUT clock cycle.

4. This applies to clock operating modes 0, 1, 2, and 3 (see table 15.2).
5. This applies to clock operating modes 8, 9, 10, and 11 (see table 15.2).
6. This applies to clock operating modes 16, 17, 18, and 19 (see table 15.2).
