Creating Non-BIOS-Managed Interrrupts on CC2650

Other Parts Discussed in Thread: CC2650, SYSBIOS

I have to much delay between Interrupt income and executing the ISR (round-about 20us). I want to reduce this time and would try with a non-bios-managed Interrupt, but I don´t know how to create such a Interrupt like these. Power Policy is disabled, so the CC2650 is not in in Power Safe mode.

Can anyone tell me how to do?

    Hi Fatih,

    To create a Non-BIOS-Managed (or zero latency) interrupt you need only create the interrupt with a priority higher than the BIOS Hwi.disablePriority.  There is a complete explanation on how to use these in the Hwi module cdoc:

    • Online cdoc
    • Use the panel on the left to navigate to: ti -> sysbios -> family -> arm -> m3 -> Hwi

    Hope this helps,
