In my application,the time base of EPWM2A and EPWM6A need to be synchronized. The EPWM2 synchrous signal output can be used as EPWM6 synchrous input? If it is OK, how to configure the register? Thanks.

ePWM2 cannot through the sync chain directly sync to ePWM6. Are you using ePWM1? Is it possible to use ePWM5 instead of ePWM2?

Thanks for your reply. In TMS320F28075(100 pin package), there is no EPWM3,EPWM4, EPWM5 PIN. So I want to use EPWM2 synchronize EPWM6.

one more question, from the datasheet， the EPWM3 cann't used to synchronize EPWM4, is that right?

Sorry for troulbing again. Can the EPWM be set as following: EPWM1 sync EPWM2,EPWM2 sync EPWM3,EPWM3 sync EPWM4,.......EPWM11 sync EPWM12, like tms2803x series?

EPWM11 can sync EPWM12. EPWM3 cannot sync EPWM4. Also in a smaller package, the EPWMx which may not have the pins available on the outside, may still be available inside of the device. This way you can shadow the configuration of a EPWM in the unused EPWM and use its syncout.
