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.

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
isrcontains 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.

Parameters
isr
