In repeat sweep mode 0, analog voltages applied to the selected pins are repeatedly converted to a
digital code. Table 15.6 shows the repeat sweep mode 0 specifications. Figure 15.12 shows the opera-
tion example in repeat sweep mode 0. Figure 15.13 shows the ADCON0 to ADCON2 registers in repeat
sweep mode 0.
