Function
Analog/Digital Converter Registers
The eight AD conversion data upper and lower registers (ADREG04H/L, ADREG15H/L,
ADREG26H/L and ADREG37H/L) store the results of AD conversion.
The two AD mode control registers control the AD converter: ADMOD0 and ADMOD1.
Figure 3.11.2 shows the registers related to the AD converter.
