==>SO CONFUSED ON FINDING A PLACE TO GET TECH SUPPORT ON   PCA9629A. <==

This appears to be a freescale forum, but its the only place I can find to ask anything.

My question is  .... I can talk to the device and read it. But the pulse width I set is WAY to low and I have no idea why.

ie the datasheet calculations are orders of magnitude off. Ramp up/Ramp down disabled. I'm thinking this has to be an obvious bonehead mYstEAK .... but I'm out of ideas.

Rewrote the code to a lower level (less complex) and it now works as advertised. Not sure exactly what I did wrong.
