It seems very low overhead, particularly in the context of the overhead of the SPI transactions themselves. I have sometimes wondered if it might be an idea to just make the core do something along these lines by default as there should be very few cases where it's important to have the suspend happen immediately. ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
