WebOct 3, 2024 · NVIC in ARM Cortex-M3 (ARMv7-M) implements fixed 8-bit priority fields in Interrupt Priority Register ( IPR ), thereby giving us up to 256 (2 8) priority levels. But, not all of the ARM Microcontrollers implement 8 bits for priority levels, in which case the remaining priority bits are treated as Zeros because the field size is fixed to 8 bits. WebThe IRQ Initialize is to initialize for common configure: gate the IRQ clock, configure enabled IRQ pins for pullup, edge select and detect mode, then enable the IRQ module. The IRQ Deinitialize is used to ungate the clock. The IRQ provides the function to enable/disable interrupts. IRQ still provides functions to get and clear IRQF flags.
