Why are all registers 0xFFFFFFFF in LPIT0 module?

[Ashlie]

Hello,

When I try to  use LPIT0 module as a periodic timer, it doesn't work at all. And then, I find that all the registers except VERID are 0xFFFFFFFF. Why?

I would really appreciate it if anyone could give me a answer.

Best regards,

Ashlie

Hi@943552732

so you're using S32K14x series MCU right?

you can take a look at the demo in S32 DS,the name is "lpit_periodic_interrupt_s32k142"

Sorry, I just find that it's the compiler display issue. The lpit0 configuration is ok. It never comes into the interrupt I want but runs into a defaultISR when I configure a interrupt enable in EBTresos as the picutre:

Maybe it's because I didn't add the interrupt handler into vector table.But what should I do for the next step?
