Note:
The resistance and capacitance for reset circuit should be designed in such a way as to ensure that the VDD is
stable and remains within a valid operating voltage range before bringing RES high.
X1 can use 6MHz or 12MHz, X1 as close OSC1 & OSC2 as possible.
Components with * are used for EMC issue.
Components with ** are used for resonator only.
