3.11.1 Analog/Digital Converter Registers
The AD converter is controlled by the three AD mode control registers: ADMOD0,
ADMOD1 and ADMOD2. The four AD conversion data result registers (ADREG0H/L to
ADREG3H/L) store the results of AD conversion.
Figure 3.11.2 shows the registers related to the AD converter.
