I have configured LPC2129 to generate PWM4 output (Single edge) at the required rate as seen in the code.I have set up a ISR for MR0 register reset.I see that Interrupt is firing only once and thereafter no more interrupts.I see on the scope prperly thePWM4 output

Atatched is the code.Please tell me why the interrupt is firing only once .

Best Regards
