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 Table 30.

The multiplexer channel to be converted can be chosen by writing the A2DChannel1[4:0] or
A2DChannel2[4:0] bits in the A2DConfigX register; the channel addresses table is reported
in the Table 31.
