GPIO interrupts

Other Parts Discussed in Thread: TPS65930

I know that a GPIO can be used to trigger an interrupt, I've used it on the DM642. I am asking the question here just to make sure that it is still true for the TPS65930/Davinci. Can you please confirm that I can use GPIOs (8 or 16) as non-maskable interrupt (NMI) ?

And is it the same as in DM642?

thanks

    Your question is a bit confusing because TPS65930 does not have any GPIO numbered 8 or 16. I am commenting on generic usage of GPIOs for masking.

    TPS65930 GPIO can be masked/unmasked using the IMR registers (Interrupt mask register). Based on this info you can use these as NMI. I am not very familiar with  NMI terminology, however, I think you can configure TPS65930 GPIOs as non-maskable interrupts. TPS

    I am not familiar with DM642 device and cannot comment on the similarity. You can ask DM642 questions on the related forum/community. Let me know if you need the link to DM642 forum and I can try to help you.
