3 | * This routine installs an interrupt vector on the target Board/CPU. |
---|
4 | * This routine is allowed to be as board dependent as necessary. |
---|
5 | * |
---|
6 | * INPUT: |
---|
7 | * handler - interrupt handler entry point |
---|
8 | * vector - vector number |
---|
9 | * type - 0 indicates raw hardware connect |
---|
10 | * 1 indicates RTEMS interrupt connect |
---|
11 | * |
---|
12 | * RETURNS: |
---|
13 | * address of previous interrupt handler |
