CONFIGURATION
AIN
Internal reference turns off after scan is complete. If
internal reference is turned off, there is a programmed
delay of 218 internal-conversion clock cycles.
00
Internal (DAC
and ADC)
Temperature
Internal reference required. There is a programmed
delay of 244 internal-conversion clock cycles for the
internal reference to settle after wake-up.
AIN6
AIN
Internal reference not used.
01
External single-
ended (REF1
for DAC and
REF2 for ADC)
Temperature
Internal reference required. There is a programmed
delay of 244 internal-conversion clock cycles for the
internal reference to settle after wake-up.
REF2
AIN
Default reference mode. Internal reference turns off
after scan is complete. If internal reference is turned
off, there is a programmed delay of 218 internal-
conversion clock cycles.

Internal (ADC)
and external
REF1 (DAC)
Temperature
Internal reference required. There is a programmed
delay of 244 internal-conversion clock cycles for the
internal reference to settle after wake-up.
