Slave Address Byte: Each slave on the I2C bus
responds to a slave address byte sent immediately
following a START condition. The slave address byte
contains the slave address in the most significant 7
bits and the R/W bit in the least significant bit. The
device’s slave address is D0h and cannot be modi-
fied by the user. When the R/W bit is 0 (such as in
D0h), the master is indicating it writes data to the
slave. If R/W = 1 (D1h in this case), the master is
indicating it wants to read from the slave. If an incor-
rect slave address is written, the device assumes the
master is communicating with another I2C device and
ignore the communication until the next START condi-
tion is sent.
Memory Address: During an I2C write operation, the
master must transmit a memory address to identify
the memory location where the slave is to store the
data. The memory address is always the second byte
transmitted during a write operation following the
slave address byte.
I2C Communication
See Figure 10 for an I2C communication example.
Writing a Single Byte to a Slave: The master must
generate a START condition, write the slave address
byte (R/W = 0), write the memory address, write
the byte of data, and generate a STOP condition.
Remember the master must read the slave’s acknowl-
edgment during all byte write operations.
Writing Multiple Bytes to a Slave: To write multiple
bytes to a slave, the master generates a START con-
dition, writes the slave address byte (R/W = 0), writes
the starting memory address, writes multiple data
bytes, and generates a STOP condition.
Reading a Single Byte from a Slave: Unlike the write
operation that uses the specified memory address
byte to define where the data is to be written, the read
operation occurs at the present value of the memory
address counter. To read a single byte from the slave,
the master generates a START condition, writes the
