Question

SPC560 - eMIOS

Hello,

I am using eMIOS module for SPC560D40L3 MCU for generating PWM. I am using default configuration for the SPCStudio project with no change to FMPLL0 and Clocks settings. My target uses 8MHz external XTAL. With this, I am trying to generate a PWM for frequency ranging from 15Hz to 600Hz. I observed that the PWM channel is not giving exact frequency PWM on the output. The difference is small at lower values but goes on increasing as the frequency rises (@ 125Hz at 600Hz). Why is this behavior for eMIOS module? Is any additional configuration required?

Thanks in advance.

Mike.
