I use the LPC1768.
I have a problem that the first pwm output PWM1.1 (P1) acts different then the other PWM output ports.
I use a period of 1 KHZ. (MR0=1000).
When I change the value for PWM1.1 port from maximum duty cycle (MR1=1001 or MR1=1000) to a new value then the first puls is always 1HKZ long and then all other pulses are the requested duty cycle.
This problem is only on PWM1.1. The other PWM ports I use don't have this problem.
Is this a known problem ?
Am I doing something wrong ?
