Hi,
As the following figure and the "WAIT IN RAM" explanation, if you select "WAIT IN RAM" as Yes, it is in polling mode, in other words, the function polls the flash status register and checks if the flash operation is complete.
If you select "WAIT IN RAM" as No, it is in interrupt mode, in other words, after the flash operation is over, an flash interrupt is triggered, and the ISR will be executed, in the ISR, the flash status variable is updated. The advantage of the method is that you can execute the other function while the flash is operated.
Hope it can help you
