DEVICE ADDRESSING
FIGURE 5-1:
CONTROL BYTE
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 24XX02, this
ALLOCATION
Read/Write Bit
is set as ‘ 1010 ’ binary for read and write operations.
The next three bits of the control byte are “don’t cares”
for the 24XX02.

The last bit of the control byte defines the operation to

selected. When set to ‘ 0 ’, a write operation is selected.
Following the Start condition, the 24XX02 monitors the
SDA bus, checking the device type identifier being
Slave Address
transmitted and, upon a ‘ 1010 ’ code, the slave device
outputs an Acknowledge signal on the SDA line.
Depending on the state of the R/W bit, the 24XX02 will
select a read or write operation.
