H7: instruction cache - what must be taken care of?

[LCE]

Heyho,

when enabling the INSTRUCTION cache in STM32H7(33), what must be taken care of?

Any cache handling required? 

Any MPU settings required?

As far as I understood that's only required for DATA cache?

No special settings, you just need to enable it. (Unless you are modifying your instructions in code, which would be very atypical.)
