TMS570LS3137: HET interrupts

$

Part Number: TMS570LS3137

Hi Team,

I am using HET module with interrupts configured as HET level 1. In micro instruction, I am expecting to get interrupt when the pulse count reaches to a 6 and pulse count is incremented using PCNT instruction.
LRP is 6.4 usec. So, ideally, i should get interrupts for every 40usec. But, i am getting interrupts around 15 usec. Can you please check this behavior and let me know your inputs?
I verified the pulse count value for every interrupt and its value is 6.
