Notes: 1. When a crystal resonator is connected to EXTAL and XTAL, the maximum frequency is
28 MHz. When a 3rd overtone crystal resonator is used, an external tank circuit is
necessary.
2. The maximum load capacitance to be connected to CKIO pin should be 50 pF in PLL2
operation, because there is a feedback from CKIO pin.
* When the oscillation settling time of a crystal resonator is lower than or equal to 1 ms.
