ADC differential mode selection register
DIFSEL | Differential mode for channels 18 to 0. These bits are set and cleared by software. They allow to select if a channel is configured as single-ended or differential mode. DIFSEL[i] = 0: ADC analog input channel is configured in single ended mode DIFSEL[i] = 1: ADC analog input channel i is configured in differential mode Note: The DIFSEL bits corresponding to channels that are either connected to a single-ended I/O port or to an internal channel must be kept their reset value (single-ended input mode). Note: The software is allowed to write these bits only when the ADC is disabled (ADCAL = 0, JADSTART = 0, JADSTP = 0, ADSTART = 0, ADSTP = 0, ADDIS = 0 and ADEN = 0). |
