Description
Legend:
DIG = Digital level output; TTL = TTL input buffer; ST = Schmitt Trigger input buffer; ANA = Analog level
input/output; I2C/SMB = I2C/SMBus input buffer; x = Don’t care (TRIS bit does not affect port direction or is
overridden for this option)
Note 1:
This functionality is only available on 44-pin devices.
