I've used DT_INTS for several years and fell madly in love with it. Lately, I'm forcing myself to get a grip on the ASM Interrupts as outlined in the "Advanced" section of the PBP Manual. Got it working on a PIC12F1501 and PIC16F18313. I intend to tackle the Vectored Interrupts with the newer offerings soon. It doesn't seem to be much more difficult than DT-INTS. Plus, I discovered you do an ASM Interrupt, part way through the ISR jump out of ASM, add some PBP, then jump back into ASM to RETFIE. I tried to alter the DT_INTS-18 for the new K42 and someone pointed out that it would require far more than just changing the SFRs to match the MCU, due to memory banks & other registers.

I'm with you, Henrik, I'm chomping at the bit to get playing with the new K42's, even ordered 2 PIC18F26K42s in anticipation.
