Hello all,

could anyone let

me know the meaning of the following remark which was found in the "Table 3-41. Cache regions" of the Kinetis "K70 Sub-Family Reference Manual"? Because of my poor English ability, I cannot understand it.

1. Cache write hits do not write-through to program flash or FlexNVM regions because flash writes require flash programming.

Does it mean that any write action will not happen when written to the program flash or FlexNVM regions?


Best regards,
