DESCRIPTION
WRITE: A low on this informs the 73K224BL that data is
available on AD0-AD7 for writing into an internal register.
Data is latched on the rising edge of
WR
. No data is written
unless both
WR
and the latched
CS
are low.

DESCRIPTION
REGISTER ADDRESS SELECTION: These lines carry
register addresses and should be valid during any read or
write operation.
SERIAL CONTROL DATA: Data for a read/write operation is
clocked in or out on the falling edge of the EXCLK pin. The
direction of data flow is controlled by the
RD
pin.
RD
low
outputs data.
RD
high inputs data.
READ: A low on this input informs the 73K224BL that data or
status information is being read by the processor. The falling
edge of the
RD
signal will initiate a read from the addressed
register. The
RD
signal must continue for eight falling edges
of EXCLK in order to read all eight bits of the referenced
register. Read data is provided LSB first. Data will not be
output unless the
RD
signal is active.
WRITE: A low on this input informs the 73K224BL that data
or status information has been shifted in through the DATA
pin and is available for writing to an internal register. The
normal procedure for a write is to shift in data LSB first on the
DATA pin for eight consecutive falling edges of EXCLK and
then to pulse
WR
low. Data is written on the rising edge of
WR
.

NOTE: The serial control mode is provided by tying ALE high and
CS
low. In this configuration AD7 becomes
DATA and AD0, AD1 and AD2 become the register address.
