Note 1: This pin is available on dsPIC33EPXXX(MC/MU)806/810/814 devices only.

2: AVDD 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 I2Câ¢ interfaces varies by device. Refer to the âPin Diagramsâ 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 âSpecial Featuresâ for more information.

6: Analog functionality is activated by enabling the USB module and is not controlled by the ANSEL register.
