Note 1: This pin is available on dsPIC33EPXXX(MC/MU)806/810/814 devices only.
2: AV
DD must be connected at all times.
3: These pins are input only on dsPIC33EPXXXMU8XX and PIC24EPXXXGU8XX devices.
4: These pins are only available on dsPIC33EPXXXMU8XX and PIC24EPXXXGU8XX devices.
5: The availability of I

C interfaces varies by device. Refer to the “Pin Diagrams” section for availability.
Selection (SDAx/ SCLx or ASDAx/ASCLx) is made using the device Configuration bits ALTI2C1 and
ALTI2C2 (FPOR<5:4>). See Section 29.0 “Special Features” for more information.
6: Analog functionality is activated by enabling the USB module and is not controlled by the ANSEL register.
