Re: [Flashforth-devel] K42 problem

[Mikael N. <mik...@fl...>]

Hi all PIC18xx K42/K83 users.
I finally managed to get the interrupts to work.

After some research and good luck it seems I found an undocumented
bug in the processor core of those chips.
By adding a NOP after every POP instruction the interrupts work in 
stable manner.

I am waiting for Microchip support to acknowledge this.
But at least FlashForth works now in a stable manner on those chips.

The vectored interrupts are not yet implemented.
