// Date:         2001-05-17
// Purpose:      Define Interrupt support
// Description:  The macros defined here provide the HAL APIs for handling
//               interrupts and the clock for the AM33-2 ASB2305 board.
//              
// Usage:
//              #include <cyg/hal/plf_intr.h>
//              ...
//
