INTERRUPT: Overview

The INTERRUPT APP is a system APP. The Cortex-M vector table contains the address of the exception handlers and interrupts service routine (ISR). It allows the user to overwrite the provided default implementation of the interrupt service routine and to set the interrupt priority.

The user needs to provide the implementation of the ISR. The user has also the choice to enable the interrupt at initialization.

The INTERRUPT APP requires the CPU APP to be informed about the number of priority levels and in case of Cortex-M4 also the number of subpriority levels.

The INTERRUPT APP based on the peripheral service request connectivity resolves the NVIC IRQ node to be used.
