Reading of result of A-D converter
In repeat sweep mode 1, all pins are used for A-D conversion with emphasis on the pin or pins selected
using the A-D sweep pin select bit. Table 1.20.6 shows the specifications of repeat sweep mode 1. Figure
1.20.8 shows the A-D control register in repeat sweep mode 1.
