PWM Register PWMEMR

Started by Klausdia December 14, 2004

I am developing a PWM on the LPC2294 with Keil PKARM, and I am facing
a problem using the PWM example of Keil. They are using the register
PWMEMR, that is not described in the datasheet of Phillips. I
contacted the support of Keil. They told me, the example was an older
version ( with wrong comments) and that they couldn't give me the
description of that register, because it was "confidential". So has
somebody in this group experience with that register or with PWM?
Thanks!

I've just recently written an app w/ PWM on the 2294. I did not use
the PWMEMR register at all. My guess is that it would be a register
that tells you the state of the output of the PWM channels (ie high or
low). Since my application seemed to work I am going to guess that it
isn't really necessary. I am also using Keil's, but I did not look at
their example code, so I don't know how they are using it.
