Note: The resistance and capacitance for the 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.
Components with *** are used for 12MHz application.
