NOTES:
1. Referenced to VCC = 2.7 to 5.5 V at Topr = -20 to 85 ° C / -40 to 85 ° C unless otherwise specified.
2. The mean output current is the mean value within 100ms.
3. The total IOL(peak) for all ports must be 80mA or less. The total IOH(peak) for all ports must be -80 mA or less.
4. Relationship among main clock oscillation frequency, PLL clock oscillation frequency and supply voltage.
