TMS320F28377D：How to shorten the time interval when emif interface writes continuous data to w5300

I want to write five consecutive data into the sending register of w5300 after the timer is interrupted at regular intervals through emif interface, but the time interval between these five data is too long, so how can we shorten the time when the read-write enable signal is set to high level between writing data? I hope my predecessors can give me advice.
