This pin is available on dsPIC33EPXXX(MC/MU)806/810/814 devices only.
AVDD must be connected at all times.
These pins are input only on dsPIC33EPXXXMU8XX and PIC24EPXXXGU8XX devices.
These pins are only available on dsPIC33EPXXXMU8XX and PIC24EPXXXGU8XX devices.
The availability of I²C™ 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.
Analog functionality is activated by enabling the USB module and is not controlled by the ANSEL register.
