Function CpuCalcCycles

source/CPU.cpp:686–694

Description: Call this when an IO-reg is accessed & accurate cycle info is needed NB. Safe to call multiple times from the same IO function handler (as 'nExecutedCycles - g_nCyclesExecuted' will be zero the 2nd time) Pre: nExecutedCycles = # of cycles executed by Cpu6502() or Cpu65C02() for this iteration of ContinueExecution() Post: g_nCyclesExecuted g_nCumulativeCycles

//	g_nCumulativeCycles
//
void CpuCalcCycles(const ULONG nExecutedCycles)
{
	// Calc # of cycles executed since this func was last called
	const ULONG nCycles = nExecutedCycles - g_nCyclesExecuted;
	_ASSERT( (LONG)nCycles >= 0 );
	g_nCumulativeCycles += nCycles;

	g_nCyclesExecuted = nExecutedCycles;
}
