Function
ADMOD1). AD conversion results are stored in four conversion result high/low register
pairs (ADREG04H/L, ADREG15H/L, ADREG26H/L and ADREG37H/L).
The AD converter is controlled by the AD mode control registers (ADMOD0 and
Figure 3.16.2 to Figure 3.16.5 show the registers related to the AD converter.
