[S32K] Flash memory setting in VLPR Mode

Hi NXP team,


The reference manual of S32K mentions that it is necessary to disable the flash module before turning off FTFC clock prior to entering VLPR mode.

There is no flash driver de-initialize code available in S32 Design Studio. So, what is the right sequence to disable the flash module?

Also, how to verify that FLASH_CLK is already less than or equal to 1MHz?


Thank you.


Best regards,

Jing Yin
