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