CC2640R2F: Util_constructClock(), configure timeout to be 0

Part Number: CC2640R2F

Hi Team,

Quick question, can Util_constructClock() configure clockDuration parameter to be 0? Will this still trigger a SWI?

Thanks!

Hi Yan,

i would expect this to be the case, yes (it will invoke the callback). Is there a special reason you would like to set this to 0?

Hi M-W,

Thanks for the reply.

I'm helping one of my customers to verify the interrupt priorities between TI-RTOS timer and SPI driver. Suppose SPI has HWI and should have higher priority than clock which is SWI, so even set clockDuration to be 0, if there is a HWI at the exact same time, it will still be preempted.

Hi Yan,

That is correct, and HWI will take priority over a SWI no matter the SWI priority used.
