/* set_vector
|
|
*
|
|
* NOTE: This function is considered OBSOLETE and may vanish soon.
|
|
* Calls to set_vector should be replaced by calls to
|
|
* rtems_interrupt_catch or _CPU_ISR_install_raw_handler.
|
|
*
|
|
* This routine installs an interrupt vector on the target Board/CPU.
|
|
* This routine is allowed to be as board dependent as necessary.
|
|
*
|
|
* INPUT:
|
|
* handler - interrupt handler entry point
|
|
* vector - vector number
|
|
* type - 0 indicates raw hardware connect
|
|
* 1 indicates RTEMS interrupt connect
|
|
*
|
|
* RETURNS:
|
|
* address of previous interrupt handler
