[1] Recommended accuracy of the clock frequency is 50 ppm for the crystal and oscillator.
[2] Suggested values for external capacitors when using a crystal are 22 pF to 27 pF.

[1] The capacitive load for each bus line (C_b) is specified in pF. To meet the specification for V_OL and the maximum rise time (300 ns), use
an external pull-up resistor with R_UP(max) = 850/C_b kΩ and R_UP(min) = (V_CC(I/O) − 0.4)/3 kΩ.
