00000 = AIN0 (default).

00001 = AIN1.

00010 = AIN2.

00011 = AIN3.

00100 = AIN4.

00101 = AIN5.

00110 = AIN6.

00111 = AIN7.

01000 to 01111 = reserved.

10000 = temperature sensor.

10001 = AVSS.

10010 = internal reference.

10011 = DGND.

10100 = (AVDD − AVSS)/6+. Use in conjunction with (AVDD − AVSS)/6− to monitor supply AVDD − AVSS.

10101 = (AVDD − AVSS)/6−. Use in conjunction with (AVDD − AVSS)/6+ to monitor supply AVDD − AVSS.

10110 = (IOVDD − DGND)/6+. Use in conjunction with (IOVDD − DGND)/6− to monitor IOVDD − DGND.

10111 = (IOVDD − DGND)/6−. Use in conjunction with (IOVDD − DGND)/6+ to monitor IOVDD − DGND.

11000 = (ALDO − AVSS)/6+. Use in conjunction with (ALDO − AVSS)/6− to monitor the analog LDO.

11001 = (ALDO − AVSS)/6−. Use in conjunction with (ALDO − AVSS)/6+ to monitor the analog LDO.

11010 = (DLDO − DGND)/6+. Use in conjunction with (DLDO − DGND)/6− to monitor the digital LDO.

11011 = (DLDO − DGND)/6−. Use in conjunction with (DLDO − DGND)/6+ to monitor the digital LDO.

11100 = V_20MV_P. Use in conjunction with V_20MV_M to apply a 20 mV p-p signal to the ADC.

11101 = V_20MV_M. Use in conjunction with V_20MV_P to apply a 20 mV p-p signal to the ADC.

11110 = reserved.

11111 = reserved.

4:0

AINM[4:0]

Negative analog input AINM input select. These bits select which of the analog inputs is connected to the negative input for this channel.

00000 = AIN0.

00001 = AIN1 (default).
