13.3.3 Rev. C
– External capacitor on AREF pin
1.) External capacitor on AREF pin
If an external capacitor is used on the analog reference pin (AREF), it should be equal to or larger than
100nF. Smaller capacitor value can make the AREF buffer unstable with large ringing which will reduce
the accuracy of the ADC.
Problem Fix/Workaround
None.
13.3.4 Rev. D to M
Not sampled.
13.3.5 Rev. N to O
No known errata.
