DT Ints not working on 16F18426

[tumbleweed]

You need to redo the section that #defines the interrupt bit locations.
It's in the section that looks like this...

  #define INT_INT      	PIR0,INTF,  PIE0,INTE       ;-- External INT
  #define IOC_INT      	PIR0,IOCIF, PIE0,IOCIE     ;-- Int On Change       *

You need to get the datasheet for the part and change the 'PIR0,INTF, PIE0,INTE' statements to match.

Somewhere along the line I got a file for the 16F18326... don't remember where or who did it.
Yours would be similar. I've attached it for ref, but I haven't checked or tested it.
