probably yes,
but with 16kbytes cache, should be possible to cache  4Kbyte instructions who generate 12Kbyte data without flushing their to main memory. e.g c2p

Agreed, but I don't know how the cache operates. For example, when the cache starts flushing data into RAM. My suspicion is that the flushing occurs as soon as possible and if that's true then you can have a stall immediately. Tests are required for that.
