When /REN1 and /REN2 are LOW, data is read
from the FIFO on every rising edge of RCLK.
Data will not be read from the FIFO if the /EF is
LOW.
When /OE is LOW, the data output bus is
active. If /OE is HIGH, the output data bus will
be in high-impedance.
Data is read from the FIFO on a rising edge of
RCLK when /REN1 and /REN2 are LOW, and
if the FIFO is not empty.

Description
When /RS is set LOW, internal read and write
pointers are set to the first location of the RAM
array, /FF and /PAF go HIGH, and /PAE and
/EF go LOW. A reset is required before an
initial WRITE after power-up.
O /FF indicates whether or not the FIFO memory
is full.
O /EF indicates whether or not the FIFO memory
is empty.
O When /PAE is LOW, the FIFO is Almost-Empty
based on the offset programmed into the FIFO.
