for the function.
Note:
When you want to make sure clock output functions are working, please check related port registers are specified. See
Set P21MD bit (bit1 of P2MOD register) to “1” for specifying the high speed clock output as the secondary function
Set P21C1 bit (bit1 of P2CON1 register) to “1” and set P21C0 bit(bit1 of P2CON0 register) to “1”, for specifying the
Data of P21D bit (bit1 of P2D register) does not affect to the high speed clock output function, so don’t care the data
