I want to add INTM to my project to monitor pit0, pit1 and an siul2 external interrupt. The period of pit0 and pit1 are 1ms and 5ms each, so I set the INTM latency of them to 15000 which leads to a latency of 250us(INM reference clock is 60MHz ) at first, but it resulted in an NCF6 error. Then I set the latency to 60000 which leads to a latency of 1ms, the error still exist. The NCF6 error disappeared until I set the latency to a huge number or disable the INTM. I think maybe I made some mistakes on the INTM setting, so I attached the setting page after the note.
Hi @jhuang1 ,
You're configuring Option B
So, PIT is running with clock: 30 MHz, INTM running with clock 60Mhz, Core clock is 120 MHz.
I tried to configurate that same with you.
Then, I have:
This is issue case:
So, please ensure that you provide enough wait time PIT interrupt before stop timer.
Best regards,
