OPERATING CONFIGURATIONS
Single Device Mode
The device must be reset before beginning operation so
that all flags are set to location zero. In the standalone case,
the RSIX line is tied HIGH and indicates single device opera-
tion to the device. The RSOX/
AEF pin defaults to AEF and
outputs the Almost-Empty and Almost-Full Flag.
Width Expansion Mode
In the cascaded case, word widths of more than 16 bits can
be achieved by using more than one device. By tying the RSOX
and RSIX pins together, as shown in Figure 11, and program-
ming which is the Least Significant Device, a cascaded serial
word is achieved. The Least Significant Device is programmed
by a LOW on the
FL/DIR pin during reset. All other devices
should be programmed HIGH on the
FL/DIR pin at reset.
Figure 10. Single Device Configuration
The Serial Data Output (SO) of each device in the serial
word must be tied together. Since the SO pin is three stated,
only the device which is currently shifting out is enabled and
driving the 1-bit bus. NOTE: After reset, the level on the
FL/DIR pin decides if the Least Significant or Most Significant
Bit is read first out of each device.
The three flag outputs, Empty (
EF), Half-Full (HF) and
Full (
FF), should be taken from the Most Significant Device (in
the example, FIFO #2). The Almost-Empty/Almost-Full flag is
not available. The RSOX pin is used for expansion.
