In one-shot mode, analog voltage applied to a selected pin is converted to a digital code once. Table 17.4
lists specifications of one-shot mode.
In repeat mode, analog voltage applied to a selected pin is repeatedly converted to a digital code. Table
17.5 lists specifications of repeat mode.

Analog voltage, applied to a pin selected by the CH2 to CH0 bits in the ADiCON0
Analog voltage, applied to a pin selected by the CH2 to CH0 bits in the ADiCON0
register (i=0, 1), is converted to a digital code once.
When the TRG bit in the ADiCON0 register is set to "0" (software trigger),
When the TRG bit is set to "1" (external trigger, hardware trigger),
• A/D conversion is completed (the ADST bit is set to "0" when the internal trigger is
• The ADST bit is set to "0" (A/D conversion stopped) by program
