input is used to write data into the FIFO. Data is written on a rising edge of WR,
the WEN input should be tied to its active state, (LOW).
or Asynchronous interface. During Synchronous operation the output port is
controlled by a Read Clock (RCLK) input and Read Enable (REN) input. Data
is read from the FIFO on every rising edge of RCLK when REN is asserted.
During Asynchronous operation only the RD input is used to read data from the
FIFO. Data is read on a rising edge of RD, the REN input should be tied to its
