In repeat mode, analog voltage applied to a selected pin is repeatedly converted to a digital code. Table
15.4 shows the repeat mode specifications. Figure 15.8 shows the operation example in repeat mode.
Figure 15.9 shows the ADCON0 to ADCON2 registers in repeat mode.

The CH2 to CH0 bits in the ADCON0 register and the ADGSEL1 to ADGSEL0
bits in the ADCON2 register select pins. Analog voltage applied to a selected
pin is repeatedly converted to a digital code
• When the TRG bit in the ADCON0 register is “0” (software trigger)
• When the TRG bit in the ADCON0 register is “1” (hardware trigger)
