Yes. the reset value of the IP (Interrupt Priority) register is 00000000b. That is, no interrupt is assigned an exceptional higher priority. The datasheets above have two IP registers (low and high). WebPriority interrupt is one of the methods of data transfer from CPU to peripheral devices Data is transferred from CPU to I/O devices on the initiation of CPU. But, the CPU cannot start the transfer unless the device is completely ready for communication with the CPU. The readiness of the device is checked only by the interrupt given by the device.

Cutting Through the Confusion with Cortex-M Interrupt Priorities

WebThe interrupt controller has a register (IRQRawStatus) that holds the raw interrupt status—the state of the interrupt signals prior to being masked by the controller.The IRQEnable register determines which interrupts are masked from the processor. This register can only be set or cleared using IRQEnableSet and IRQEnableClear. Table 9.10 … WebThis device emulates the XICS (eXternal Interrupt Controller Specification) defined in PAPR.
