#S32K144 Cache write Test

##S32K144 support modifying cache values? Why is it that after I modify a value, reading the same address still returns the original value? Additionally, can the cache's parity bit be tested？thanks

Hi @joshua9264,

It is technically possible to change the cache value through the LMEN registers.

Let me create a simple test project.
