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. For other interrupts, software writes to the GICD_IPRIORITYRn registers to set the interrupt priorities. Witryna1 paź 2024 · Assign PIE group priority levels GxyPL (where x = PIE group number 1 - 12 and y = interrupt number 1 - 8) These values are used to assign a priority level to each of the 8 interrupts within a PIE group. A value of 1 is the highest priority while a value of 8 is the lowest. More then one interrupt can be assigned the same priority level. port dover live cams

WitrynaTo configure the priority of an interrupt, we can take advantage of the fact that the interrupt priority registers are byte addressable, making the coding much easier.
