Center-Aligned PWN with S08TPMv3

Hi!

I'm working with MCF51QE, and I'd like to generate some tones using PWM, more over, center-alinged PWM.

The problem is that I could only generate 1 periodo (only one transition), and I want it to be continuous.

What I do is:

TPM0SC = 0x68;

TPM0C2SC = 0x00;

TPM0MOD = MOD_val;

TPM0C2V = MOD_val;

What should I do for the PWM to be continuous? I guess it could be related to the TOF IRQ.. I try setting MOD value again, setting V value again, and setting both value and nothing happens

Thanks in advance!!

Have you downloaded the QE128QUG and the accompanying QE128QUG software from theMCF51QE page?

I haven't looked inside this, but it looks like a start.
