The MCUXpresso SDK provides a peripheral driver for the external interrupt (IRQ) module of MCUXpresso SDK devices.

IRQ Operations

IRQ Initialization Operation

The 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.

IRQ Basic Operation

The IRQ provides the function to enable/disable interrupts. IRQ still provides functions to get and clear IRQF flags.

Typical use case
