External clock input
Note1: The external oscillator circuit must be directly from Vss pin of micro-controller.
Note2: The input source of XIN pin received from external oscillator circuit, the code option can be either
be RC type oscillator or crystal type oscillator.
Note3: In RC type oscillator code option situation, the external clock frequency is automatically divided
by 2.
