i want to interface two peripheris at the microcontroller mcf52223. An ADU and a memory chip.
The QSPI generate the  chip selct signal  to start the conversion of the ADU in wrap around modus.
Data were only read from the ADU. The QSPI write only any data (no ADU data) to the memory chip.

cs0 start conversion ADU  and cs1 select memory chip to write.

I want to use each peripheri at the same time: write Datat to memory and read Data from ADU

Can I send cs0 and cs1 signals at the SAME  time to the ADU and memory chip?

Thanks for help.
