I try to use the timer for a Delta-Modulation to drive a Motor-Controller.
As the LPC has only 1 PWM I can't use it because I need four different frequencys.

I implement 1 Timer and all works fine with a constant frequency, but if I change it up to a sensor value suddenly (but not immediately, so I can change the speed of the motor) the Pulse is away.
Up to the debugger nothing change but the IR:MR0I is constant 0. The TC and PC are still counting but the interrupt routine is not anymore entering.

Have anyone an idea what this could cause?
Are you need my code?

Thanks, Tim

I found a solution. Everytime I  change the frequency I reset, init and enable the timer.
Maybe this help someone else.
