This is obviously due them being named in the XML file that

But I agree, the datasheet mentions them as PCINT0, PCINT1,
and PCINT2, respectively, so our header file should follow

Please file a bug report at Atmel for the discrepancy between
the datasheet and the XML file.

The compiler cannot generate an error for a misspelled vector
name, but it is supposed to generate a warning.

The om Interrupt Vectors are missing from the libc documentation. This would be important, as the pcints are defined in an inconsistent way! Rather than PCINT1_vec oder PCInt0_vec they have been defined as PCInt_A_vec, PCINT_B_vec and PCINT_D_vec corresponding to the ports involved. This is different to all other implementations, and, sadly, calling PCInt0_vec will be accepted by the compiler and cause a mc reset - strange!

I think this behaviour should be reflected in the libc documentation!

Kind regards,

S. Levedag
