I've inherited an old project and adding ISR routines to IRQ1-IRQ7 pins of the 5213. Pretty sure I have the EPORT configured properly since I do enter the ISR but can only enter once. I'm running on an old freescale Evaluation board. (the one with 3 pushbuttons connected to IRQ1, IRQ2 and IRQ3). Old freescale app notes refer to EPORTSoftwareDemo.zip which contains source for ISR examples but that file is no longer around.
Any help explaining the proper EOI sequence will be appreciated
