How to use the internal watchdog timer of the embedded flash memory in S32K3x?

[Chris-Sun]

Currently, I am using the Flash module of the S32K312 chip.

According to the chip manual, there is an internal watchdog available for the Flash module, and it can be configured through the AMCR register.

However, I could not find the documentation for the corresponding configuration registers. Where can I find the description of the AMCR and AMCRS register? What is its functionality? How should we configure this watchdog feature?

Hi @danielmartynek 

Thank you for your response to my post.

According to the topic you mentioned, the reply inside is "All the HSE_B, HSE_FW information is available in Secure Files under NDA."

Could you please explain what "Secure Files under NDA" refers to?

Do I need to configure it in a special way?

Could you please provide specific instructions on how to operate this, as I am not very familiar with this part of the information.

Thanks a lot.

Best regards,
Chris

Your response resolved my confusion.

I will create a new topic to discuss HSE if necessary.
