s32K144 FlexNVM cache is not updated.

S32K144 writes to FLexNVM, and then reads it immediately, and the data will be incorrect. Read a other address and read it, will get the right result. I guess it should be that cache is not updated.
How to update the cache or temporary close of the manual FlexNVM?

Hi,

This happens when the DFlash prefetch buffer is not disabled in OCMDR1 register before reprogramming the data.
