In repeat sweep mode 1, analog voltage is applied to the all selected pins are converted to a digital code,
with mainly used in the selected pins. Table 15.7 shows the repeat sweep mode 1 specifications. Figure
15.14 shows the operation example in repeat sweep mode 1. Figure 15.15 shows the ADCON0 to
ADCON2 registers in repeat sweep mode 1.

The SCAN1 to SCAN0 bits in the ADCON1 register and the ADGSEL1 to
ADGSEL0 bits in the ADCON2 register mainly select pins. Analog voltage
applied to the all selected pins is repeatedly converted to a digital code
