Legend:
Note 1:
2:
DIG = Digital level output; TTL = TTL input buffer; ST = Schmitt Trigger input buffer; ANA = Analog level
input/output; x = Don’t care (TRIS bit does not affect port direction or is overridden for this option)
Pins are configured as analog inputs by default on POR. Using these pins for digital inputs requires setting
the appropriate bits in the ANCONx register first.
All other pin functions are disabled when ICSP™ or MPLAB^® ICD are enabled.
3: This functionality is only available on 44-pin devices.
