AM2634-Q1: PWMSYNC source selection for CMPSS ramp trigger

Sung-IL

Part Number: AM2634-Q1
Other Parts Discussed in Thread: SYSCONFIG

Dear Champs,

My customer has used F28003x for their application and now trying to use AM263x for same application, but could not find PWMSYNC Source Select menu in sysconfig to ramp trigger of CMPSS.

In F28003x, they select PWMSYNC Source in sysconfig as below.

But, they could not find it in AM263x sysconfig.

Could you please guide how they can set PWMSYNC Source to ramp trigger of CMPSS in AM263x?

Thanks and Best Regards,

SI.

Their application is PCMC(Peak Current Mode Control) and they need it to trigger the ramp of CMPSS.

Thanks and Best Regards,

HI SI,

The EPWMPERSYNC register set was defined in the HRPWM register space, though HRPWM has no impact on this control. The syscfg had the API sorted in terms of the Register set, hence its not seen in the Time Base submodule.

Thanks for pointing out. this is a known issue and we are fixing this in the next release. please find it here with the following steps in the syscfg until then.

Thanks and regards,
Madhava
