Pin change interrupt on D10

[Papafelice]

The datasheet is wrong on page 88, PCICR, Bit PCIE1 states PCINT[14:8], but this should be PCINT[15:8], because D10 (PC7) corresponds to PCINT15 and this pin does generate an interrupt.

I added pin D10 to the header file like this:

#define digitalPinToPCICRbit(p) ( ((p) == 5  || (p) == 6) || \
                                  ((p) == 8  || (p) == 9) || \
                                  ((p) == 17)             || \
                                  ((p) >= 21 && (p) <=23) ? 0 : \
                                ( ((p) >=  2 && (p) <= 4) || \
                                  ((p) == 12 || (p) ==10) || \
                                  ((p) >= 18 && (p) <=20) ? 1 : \
                                2))

#define digitalPinToPCMSK(p)    ( ((p) == 5  || (p) == 6) || \
                                  ((p) == 8  || (p) == 9) || \
                                  ((p) == 17)             || \
                                  ((p) >= 21 && (p) <=23) ? (&PCMSK0) : \
                                ( ((p) >=  2 && (p) <= 4) || \
                                  ((p) == 12 || (p) ==10) || \
                                  ((p) >= 18 && (p) <=20) ? (&PCMSK1) : \
                                (&PCMSK2)))

and the interrupt works fine. Is this remark:

// Port D10 does not support Soft Serial

only due to the flaw in data sheet? With this patch it could then be removed.

@Papafelice Hello. Just noting your comment. Will you be submitting a Github push with your validated changes?

As to the note: "Port D10 does....", it was so long ago I can not really say. Am guessing this was a note picked up when the origin Soft Serial work, and per your speculation likely from the Datasheet issue you noted. If indeed D10 will work, then agree -- comment should also be removed.

Thank you!
