// Author(s):    nickg
// Contributors: nickg, jskov, gthomas, jlarmour
// Date:         2001-03-21
// Purpose:      NEC V850 Interrupt support
// Description:  The macros defined here provide the HAL APIs for handling
//               interrupts and the clock for variants of the NEC V85x
//               architecture.
//              
// Usage:
//              #include <cyg/hal/var_intr.h>
//              ...
//
