WitrynaAn implementation might reserve an interrupt for a particular purpose and assign a fixed priority to that interrupt, meaning the priority value for that interrupt is read-only. This model aligns with the priority grouping mechanism described in Priority grouping. noteshelf cross platformWitrynaIt is worth noting that nested interrupt handling is a choice made by the software, by virtue of interrupt priority configuration and interrupt control, rather than imposed by hardware.
