Timer Problem

I'm working with the ST72264G u-C.

I'm using Timer A in ''one pulse mode'', and I want to use Timer B as ''output compare'' to indicate when a period of time has elapsed without output pin. (just to get interrupt when a period has elapsed).

In my application I want Timer B to be stopped until I enable it wait for the output compare interrupt and disable it back.

Since Timer B is free running, when I enable the interrupts using ''rim'' I get a timer B interrupt although I already set the TIMD bit in the CSR (and preformed a read from the CSR/OCBLR to clear the OCF bit).

Can anyone advise how the get rid from the first unwanted interrupt?

It is not the normal behaviour. Could you attach your code ?

I suspected that I worked with a faulty chip.

I replaced it and everything is working.

Thanks
