A control byte is the first byte received following the
Start condition from the master device. The control byte
consists of a four-bit control code. For the 24XX01, this
is set as ‘
The next three bits of the control byte are “don’t cares”
for the 24XX01.
The last bit of the control byte defines the operation to
be performed. When set to ‘
selected. When set to ‘
Following the Start condition, the 24XX01 monitors the
SDA bus, checking the device type identifier being
transmitted. Upon receiving a ‘
device outputs an Acknowledge signal on the SDA line.
Depending on the state of the R/W bit, the 24XX01 will
select a read or write operation.
