But since you specified a priority for the PO (and assuming priority_ceiling), you still execute at interrupt priority. Depending on the hardware and how priorities are managed, this may delay or hide actual interrupts.


Are you saying it may be better not to specify a priority?

Not exactly. If your compiler doesn't use priority_ceiling by default (and you didn't specify it), then the priority is ignored.

Otherwise, the default priority of a protected object is Priority'Last (D.3(11)), which will result in ceiling violation if called from a PO which has a priority in the Interrupt_Priority range. You should then specify a priority at least as high as the one of the other PO.
