Center-Aligned PWN with S08TPMv3

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!!
