GPIOn interrupt for C6678

murad qahwash

Hello All,

Is it possible to use GPIO3 to interrupt Core0 in C6678 DSP...Event 90 says when using GPINTn, CorePac[n] will receive GPINTn...does that mean that we can't use GPIO[0:7] other than GPIO0 to interrupt Core0?

Hi,

It is not possible. Better to use core specific GPIO pin or other GPIO interrupt pins(except GPIO0-7).

Thanks,

Thanks alot Ganapathi for your prompt response...what do you mean by "core specific GPIO pin"?

GPIO0 interrupt mapped to Core0, GPIO1 interrupt mapped to Core1, GPIO2 interrupt mapped to Core2,.... GPIO7 interrupt mapped to Core7.
