Simulation of Periperals in Keil for Philips 89CR51C+

hello,
I am trying to use timer2 for timer ticks as well as detecting edge detection at t2ex pin.

When i am doing the simulation for edge detection i donot see any response from the debugger like interrupt flag / vectoring to ISR. When i set edge detection IRQ, vectoring to ISR occurs. Timer tick the vectoring occurs for timer overflows.

T2CON=0x09;  
TH2=0xff;
TL2=0xf0;
TR2=1;       

ET2=1;       
EA =1;

Similar problem is being faced by me when i try to use pca modules for edge detection.

Simulation at External interrupt pins is working normally.

simulation dll version is v2.01.

If any body could explain the behaviour of the software simulation, i shall be glad to them.
thanking in advance

I don't recall that problem, but your DLL Version sounds really old. Get the latest update from http://www.keil.com/update and that should correct the problem.
