Note 1: Setting the RPORx register with the listed value assigns that output function to the associated RPn pin.
2: The NULL function is assigned to all RPn outputs at device Reset and disables the RPn output function.
3: IrDA
®
BCLK functionality uses this output.
4: SCK1OUT can also be specifically mapped to the ASCK1 pin by setting the SCK1CM bit (ALTRP[0]). See
Section 10.4.3.3 “Alternate Fixed Pin Mapping” for more information.
