Mega2560 Interupts for Analogs 6-15

Projects Programming

I have interrupts working on Pins 10 and 11 using: ISR (PCINT10_vect){ but I cannot figure out what group to use for analog pins A6 - A15

I see where these intterupt groups are referenced for the 328 on Nick gammons site:

4 Pin Change Interrupt Request 0 (pins D8 to D13) (PCINT0_vect)
5 Pin Change Interrupt Request 1 (pins A0 to A5) (PCINT1_vect)
6 Pin Change Interrupt Request 2 (pins D0 to D7) (PCINT2_vect)

However I've been combing through this mapping page:

and the datasheet http://www.atmel.com/images/atmel-2549-8-bit-avr-microcontroller-atmega640-1280-1281-2560-2561_datasheet.pdf

But I am unable to determine what the interrupt is for say A12.

Thanks for any help.

Well.. just testing through different interrupts, I found that A9-12 are all part of PCINT2_vect . So at least now I can make that work, but I would appreciate someone explaining how to figure that out from the documentation.

Thanks.

Thank you. I'll dig into that.
