Description
Legend: 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)
Note 1: 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.
2: All other pin functions are disabled when ICSP™ or MPLAB
®
ICD are enabled.
3: This functionality is only available on 44-pin devices.
