The A2D system is enabled by setting the A2DEnable bit to ‘1’ in the A2DControl register.

The A2DType bit in the A2DConfigX registers selects the A2D active configuration (8-bit 
resolution or 9-bit) according to the 

.

         

The multiplexer channel to be converted can be chosen by writing the A2DChannel1[4:0] or
