FUNCTIONAL DESCRIPTION
Parallel Data Input
The device must be reset before beginning operation so
that all flags are set to their initial state. In width or depth
expansion the First Load pin (
FL
) must be programmed to
indicate the first device.
The data is written into the FIFO in parallel through the D
0–
15
input data lines. A write cycle is initiated on the falling edge
of the Write (
W
) signal provided the Full Flag (
FF
) is not
asserted. If the
W
signal changes from HIGH-to-LOW and the
Full Flag (
FF
) is already set, the write line is internally inhibited
internally from incrementing the write pointer and no write
operation occurs.
Data set-up and hold times must be met with respect to the
rising edge of Write. On the rising edge of
W
, the write pointer
is incremented. Write operations can occur simultaneously or
asynchronously with read operations.
Serial Data Output
The serial data is output on the SO pin. The data is clocked
out on the rising edge of SOCP providing the Empty Flag (
EF
)
is not asserted. If the Empty Flag is asserted then the next data
word is inhibited from moving to the output register and being
clocked out by SOCP.
The serial word is shifted out Least Significant Bit or Most
Significant Bit first, depending on the
FL
/DIR level during
operation. A LOW on DIR will cause the Least Significant Bit
to be read out first. A HIGH on DIR will cause the Most
Significant Bit to be read out first.
