Pic16F1828 interrupts

According to the data sheet all enabled pins on PortA and PortB respond to Interrupt on Change but looking at the 16F1828 header file I only see an Int_RB choice. Does this respond to all enabled bits on PortA and PortB? If not, what is the interrupt choice for PortA?
Thanks,
Dave

You didn't say what version you are using but 4.130 has the INT_RA entry in the header.
BTW, the file INTS.TXT shows all the possible options for interrupts.

BTW, where/what is ints.txt? I can't find it in my installation or on a search of the ccsinfo site.

It's in the PICC directory where the compiler resides. If you don't have
the IDE you may not have it or the fuses.txt file.

I certainly have fuses.txt but no ints.txt I use MPLAB as the IDE so that may be it. I just updated everything I could find even including ccload but still no ints.txt. Thanks again for the help.

I would drop a line to CCS and ask them for it. Since they have
always been nice when I have contacted them I expect they might just
send it to you.

It is 'Ints.txt', with a capital 'I'. Some programs sort it differently because of this. It is present in every version of CCS I have ever seen. Looked back to 2002, and not one version has it missing.
