Hi,
I configure F28027 generates an interrupt, when the ePWM1 counter equal to zero. But, there is a delay time between pwm1 signal and jumping interrupt. about ~2usn. (Code is on flash)
When I only move ISR routine to RAM, delay time is 0.6~0.7us. There is same problem on PWM trigger ADC_SOCx. (I works with C2000 Launchpad.)
Switching period, 10us, therefore this delay is a problem. How can i overcome this ?
Best Regards,
