18.4.13 Operation During Power-Saving Modes

The power-saving modes, Sleep and Idle, are useful for reducing the conversion noise by minimizing the digital activity of the CPU, buses and other peripherals.

To reduce the current consumption when the ADC is idle, the converter can be configured to a stand-by mode using the STNDBY bit (ADnCON[16]). When the STNDBY bit is set, the ADC enters the power-saving mode. The status OMODE[1:0] bits (ADnCON[25:24]) are switched to ‘01’ when the ADC is in stand-by state.
