operation whereas the falling clock edges triggers the write operation.
data_a
All memory blocks support simple dual-port mode. Simple dual-port mode allows
you to perform one-read and one-write operation to different locations at the same
time. The write operation occurs on port A; the read operation occurs on port B.
