你问的是HCS12 CORE的中断还是XGATE的中断?
实际上使用codewarrior新建一个工程,或者参考demo工程就可以了.
static void SetupXGATE(void) {
/* initialize the XGATE vector block and
set the XGVBR register to its start address */
XGVBR= (unsigned int)(void*__far)(XGATE_VectorTable - XGATE_VECTOR_OFFSET);
/* switch software trigger 0 interrupt to XGATE */
ROUTE_INTERRUPT(SOFTWARETRIGGER0_VEC, 0x81); /* RQST=1 and PRIO=1 */
/* enable XGATE mode and interrupts */
XGMCTL= 0xFBC1; /* XGE | XGFRZ | XGIE */
/* force execution of software trigger 0 handler */
XGSWT= 0x0101;
}
const XGATE_TableEntry XGATE_VectorTable[] = {
// Channel # = Vector address / 2
/* channel 0..8 are not used, first used must match macro XGATE_VECTOR_OFFSET in xgate.h */
{ErrorHandler, 0x09}, // Channel 09 - Reserved
{ErrorHandler, 0x0A}, // Channel 0A - Reserved
{ErrorHandler, 0x0B}, // Channel 0B - Reserved
{ErrorHandler, 0x0C}, // Channel 0C - Reserved
{ErrorHandler, 0x0D}, // Channel 0D - Reserved
{ErrorHandler, 0x0E}, // Channel 0E - Reserved
......
