Can a quad-spi flash chip be written at a same time that the code is run from it?

We are investigating for a new STM32F7 based device with QSPI FLASH as a main memory to run the application from (XIP).

We also need FLASH memory for mass storage, and what is not clear for us is if we can use the same QSPI memory chip for mass storage also. I.e. can we write/read the QSPI chip at the same time that we are running the code from it?
