static void __ARHandler(u32 irq,void *ctx)
{
	__ARClearInterrupt();

	if(__ARDmaCallback)
		__ARDmaCallback();
}

static void __ARHandler()
{
#ifdef _AR_DEBUG
	printf("__ARHandler()\n");
#endif
	__ARClearInterrupt();
	
	if(__ARDmaCallback)
		__ARDmaCallback();
}

Example #3

{
	// set main memory address
	_dspReg[16] = (_dspReg[16]&~0x03ff)|_SHIFTR(memaddr,16,16);
