Detailed Description

This file implements interrupt dispatcher. Most of the code is taken from the 533 implementation for blackfin. Since 52X supports 56 line and 2 ISR registers some portion is written twice.

Function Documentation

◆ bfin_interrupt_init()

void bfin_interrupt_init ( void )

Initializes the interrupt module

The bf52x has 8 IAR registers but they do not have a constant pitch.

◆ bfin_interrupt_register()

rtems_status_code bfin_interrupt_register ( bfin_isr_t * isr )

This routine registers a new ISR. It will write a new entry to the IVT table

Parameters

isr	contains a callback function and source

Returns: rtems status code

◆ bfin_interrupt_unregister()

rtems_status_code bfin_interrupt_unregister ( bfin_isr_t * isr )

This function unregisters a registered interrupt handler.
