How to set RAMPSOURCE in F28069 comparator

Other Parts Discussed in Thread: CONTROLSUITE

Hi,

According to the description of ADC manual (spruge8e), I can select the PWMSYNC source from HRPCTL.bit.PWMSYNCSEL ,but the manual spruge8e is designed for TMS320x2802x, 2803x.

I investigate TMS320x2806x Piccolo Technical Reference Manual and ControlSUITE

finding that the bit PWMSYNCSEL is nonexistent at all in F28069.

Now my question is: where can I get the signal PWMSYNC in F28069.

Thanks,

If you check the DAC Control (DACCTL) Register in TRM, here is how you can select PWMSYNCx signals:

Hi Gautam,

Thanks for your reply.

I know the DACCTL Register can select PWMSYNCx signals,

but What I want to konw is : where the PWMSYNCx signals come from ?

Specifically, What is the Register that manage the PWMSYNCx or How can I generate the signals ?

Thanks you.
