WebRunning Priority Register, GICC_RPR The GICC_RPR characteristics are: Purpose Indicates the Running priority of the CPU interface. Usage constraints If there is no active interrupt on the CPU interface, the value returned is the Idle priority. Note Software cannot determine the number of implemented priority bits from a read of this register. WebEach peripheral priority register consists of a configurable preemption field and a subpriority field. The least significant bit (LSB) is the subpriority bit. If two interrupts are raised with the same preemption level, the interrupt with the lowest subpriority level will be served first.
