Detailed Description

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

Enumeration Type Documentation

◆ e_isr_t

enum e_isr_t

The type of interrupts handled by the SIC

Function Documentation

◆ bfin_interrupt_init()

void bfin_interrupt_init ( void )

blackfin interrupt initialization routine. It initializes the bfin ISR dispatcher. It will also create SIC CEC map which will be used for identifying the ISR.

◆ 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.
