PIE on the TMS320F2812 - rising or falling edge triggered?

Julian Woloszczuk

Hello,   I'm writing some driver software for the above device, so we have some flexible, re-usable code. With my previous experience with interrupts, I expect there to be a way to set how the interrupt is triggered, namely rising or falling edge. I can see this setting for the external interrupts, but not for 'pie' interrups. Am I missing something here?  Thanks for your help,   Julian.

    The PIE interrupt signals are generated within each of the Peripherals.  Within each Peripheral, it may be possible to specify things like rising or falling edge triggers.  The PIE simply handles the processing of the interrupts once sent.
