TMS320F28379D: CLA and Interrupt

Part Number: TMS320F28379D

1. What is the minimum frequency that the epwm interrupt can get activated? I tried to Generate EPWM interrupt at every 500ns but it was failed.

2. What is the minimum frequency that a CLA task can be triggered?

Well the configuration could allow you to enable the interrupts at those speeds but it is not recommended for an application. If the EPWM interrupt occurs that rapidly, + delay to enter the ISR, couple instructions to clear the interrupt flags + ACK the PIE, you are left with barely any cycles... before the next interrupt comes.
