DESCRIPTION (CONTINUED)
register has a flag to signal when new mail has been stored. Two or more
devices may be used in parallel to create wider data paths. Expansion is
also possible in word depth.
synchronous interface. All data transfers through a port are gated to the
LOW-to-HIGH transition of a continuous (free-running) port clock by en-
able signals. The continuous clocks for each port are independent of one

two-stage synchronized to CLKA. The Output Ready (OR) flag and Al-
most-Empty (AE) flag of the FIFO are two-stage synchronized to CLKB.
Offset values for the Almost-Full and Almost-Empty flags of the FIFO can be
programmed from port A or through a serial input.
The Input Ready (IR) flag and Almost-Full (AF) flag of the FIFO are
