Using SPI0 for internal flash and external ADC


I'm using a BF512F. It has internal flash, which I'm loading my code onto using a flash programmer. The internal flash is connected to the Blackfin via the SPI0. I also want to run an ADC off the SPI0. Is this possible? My understanding is that when the processor is reset, all the required code in the flash is booted into the Blackfin's SRAM, leaving the SPI0 free to be used as a peripheral.

Thanks for your insight!
