Figure 24. A2D block diagram
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 Tab le 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 Ta bl e 31 .
