how to switch back from PSRAM to FLASH in xmc4500 ???

Hi,
I am working on xmc4500, i flashed the bin file to PSRAM using ASCBSL mode successfully. now i want to write the data into flash location and run it without switching the TMS TCK pins. can i exectue the flash code ???

actually my intention was

from PSRAM i will receive data and i will write that data into flash location.
after writing into flash i want to execute it.

Thanks and Regards,
