WFE/WFI and pending interrupts?

I'd like to know the behavior of WFE and WFI regarding pending interrupts that occur prior to these instructions, on 2 different Cortex profiles. In both cases, t he goal is to ensure any incoming interrupt...

Can wfe/sev instruction work between 64 & 32 bit cores?

Hi Expert, In a multicore system, core1(64bit mode) is pending by wfe instruction. If core0(this is also a 64bit core but it switched from 64 to 32bit mode) run sev instruction, can core1 be waked up...

Race condition between wake up event and WFI on Cortex-M3/M4

When I read below thread in arm forum, I still not clear which one is the safety way. Cortex-M4: guaranteed wakeup from WFI? There're two solutions mentioned above, using WFE instead of WFI, and swap...
