Hi

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 acknowledge the interrupt in ISR

I see on the scope prperly thePWM4 output

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

Best Regards
Anand
