Use the RTCSS 7GPIO to replace the key scan

Hi All:

We want to use the RTCSS 7GPIO to replace the key scan on IPNC DM368.

And we want to check if we can use the RTCSS interrupt function.

Is that any issue or risk we should take care?

Best Regards,

Justin,

Your use-case should work fine. It can generate interrupt from GIO. See the documentation SPRUFJ0A.

"The PRTCSS module outputs a single interrupt RTCINT that is routed to the DM36x interrupt controller. The INTC supports interrupts from GIO signals and interrupts from RTC signals."
