STM32F745 Synchronization with GPIO

Hey world! I use STM32F745 in my project. High-speed ADC connected to GPIO port. ADC and MCU clock from 25 MHz generator. Also clock signal goes to GPIO port. The MCU clock frequency is 200 MHz. I've realized the transmission  ADC-to-memory MCU due to assembler insertion with 40 ns (25 MHz). But the problem is to synchronize with rising-edge of external 25 MHz generator. Does anybody knows how to realize the beginning of assembler insertion execution with rising-edge of external generator? Any help appreciated!)
