CCS/TMS320F28377D: ePWM ownership in dual cpu

Hi,

1. Is each CPU has their own ePWM1~12 ? (which means there is total 24 ePWM modules)

No, there are only 12 ePWM. User can assigned each of them to either CPU1 or CPU2 by configuring the CPUSEL.

2. if there is only 12 ePWM module in 28377, then what is the ownership of the INT trigger and PWM output?

Interrupt are sent to both the CPU irrespective of the IP ownership. User can disable the interrupt inside PIE if not needed on a CPU.

3. following question2, how to set ePWM module ownership to CPUs?

Explained in point # 1.
