Question about LPC2103 PWM

I have a question about the 16-bit PWM on the LPC2103 family, and right now I don’t have any hardware available to answer the question.

In section 5.13 of the user manual it states "All single edge controlled PWM outputs go LOW at the beginning of each PWM cycle

(timer is set to zero) unless their match value is equal to zero."

My question is, will manually setting the timer to zero cause the PWM outputs to go low, or does it need to be a timer reset caused by a match with reset on MR enabled?

The reason I need to know this is because I need to generate PWM pulses not periodically but based on external events.

Thanks,

Mike
