Note1: The VDD and VSS of external oscillator circuit must be from micro-controller. Don’t connect them
from power terminal.
Note2: The external clock input mode can select RC type oscillator or crystal type oscillator of the code
option and input the external clock into XIN pin.
Note3: In RC type oscillator code option situation, the external clock frequency is divided by 2.
