    No, you don't need to remap the pins. It is a dual example. He show both " so I'm posting a simple example here showing how to use the RTCC, and how to assign PWM to several pins."

    For you, you can just look at the RTC part.

    From the data sheet under RTCC
    • Requirements: external 32.768 kHz clock crystal
    Code:
      ' Connect a 32.768 kHz watch crystal between pins 11 & 12 T1CKI & T1OSI
      ' with caps to match your crystal load capacitance.
      ' 11        12

    Any idea where I can get the 12.5pf capacitors? I have checked all my online suppliers and can't find them.
