C/C++ atomic operation on ARM9 and ARM Cortex-M4

I have a question about C/C++ atomic operation on ARM9 and ARM Cortex-M4. I am using ARMCC compiler with C / C++ languages. It interests me if it is possible that an interrupt will be handled in the middle...

Atomic block - intterupts proof on cortex-M3

Hi, I'm looking for solution, how to make atomic execution block on Cortex-M3 uC. What is the best solution for this? Best regards, Lukas
why cortex m3 bit manipulation is atomic

As far as I know, atomic operation are those which can not be interrupted. It implies that that they are single cycle operation. Because any operation having more than one cycle can be interrupted if...
