C++ (Cpp) ZetLowerIrq Examples

Example #1

File: d_twinhawk.cpp Project: SiN13/pifba

void twinhawkYM2151IRQHandler(int irq )
{
	if (irq)
	{
		ZetRaiseIrq(1);
	}
	else
	{
		ZetLowerIrq();
	}
}

Example #2

File: qs.cpp Project: tmaul/finalburnalpha_2001

int QsndSectRun(int nStart,int nEnd)
{
	int nTo;
	// See if an irq occurs before the end
	while (nStart+nIrqNext<nEnd)
	{
		nTo=nStart+nIrqNext;
		SectRun(nStart,nTo);
		ZetRaiseIrq(0xff);
		ZetRun(0);
		ZetLowerIrq();

		nIrqNext=nIrqPeriod; // Next irq happens after period
		nStart=nTo; // Done this part now
	}

	nTo=nEnd;
	SectRun(nStart,nTo);
	nIrqNext-=nTo-nStart; // Next irq happens sooner
	return 0;
