Note:
  1. Refer to the “Fixed Voltage Reference Module” chapter for more details.
  2. Refer to the “Digital-to-Analog Converter Module” chapter for more details.
  3. Refer to the “Temperature Indicator Module” chapter for more details.
  4. 20-pin devices only.
  5. 14-pin devices only.
  6. This configuration routes the specified analog channel to the noninverting input of the OPA module (OPAxIN+), and connects the output of the OPA (OPAxOUT) to the input of the ADC for conversion. The OPA module must be configured accordingly to use this mode of operation. Refer to the "OPA - Analog Signal Conditioning" chapter for more details.
