Notes: 1. When a crystal resonator is connected to EXTAL and XTAL, the maximum frequency is
34MHz. when a 3rd overtone crystal resonator is used, an external tank circuit is
necessary.
2. The load capacitance connected to the CLKOUT pin should be a maximum of 50 pF.
3. t_cyc shows 1 cycle time of a CLKOUT clock.
