7.3.5 Writing and Reading Operation
Accessing a particular register on the TMP102 device is accomplished by writing the appropriate value to the
pointer register. The value for the pointer register is the first byte transferred after the slave address byte with the
R/W bit low. Every write operation to the TMP102 device requires a value for the pointer register (see Figure 8).
When reading from the TMP102 device, the last value stored in the pointer register by a write operation
determines which register is read by a read operation. To change the register pointer for a read operation, a new
value must be written to the pointer register. This action is accomplished by issuing a slave address byte with the
R/W bit low, followed by the pointer register byte. No additional data are required. The master then generates a
START condition and sends the slave address byte with the R/W bit high to initiate the read command. See
Figure 7 for details of this sequence. If repeated reads from the same register are desired, continually sending
the Pointer Register bytes is not necessary because the TMP102 remembers the Pointer Register value until it is
changed by the next write operation.
Register bytes are sent with the most significant byte first, followed by the least significant byte.
7.3.6 Slave Mode Operations
The TMP102 can operate as a slave receiver or slave transmitter. As a slave device, the TMP102 never drives
the SCL line.
7.3.6.1 Slave Receiver Mode
The first byte transmitted by the master is the slave address, with the R/W bit low. The TMP102 then
acknowledges reception of a valid address. The next byte transmitted by the master is the pointer register. The
TMP102 then acknowledges reception of the pointer register byte. The next byte or bytes are written to the
register addressed by the pointer register. The TMP102 acknowledges reception of each data byte. The master
can terminate data transfer by generating a START or STOP condition..
7.3.6.2 Slave Transmitter Mode
The first byte transmitted by the master is the slave address, with the R/W bit high. The slave acknowledges
reception of a valid slave address. The next byte is transmitted by the slave and is the most significant byte of
the register indicated by the pointer register. The master acknowledges reception of the data byte. The next byte
transmitted by the slave is the least significant byte. The master acknowledges reception of the data byte. The
master terminates data transfer by generating a Not-Acknowledge on reception of any data byte, or generating a
START or STOP condition.
7.3.7 SMBus Alert Function
The TMP102 device supports the SMBus alert function. When the TMP102 device operates in Interrupt Mode
(TM = 1), the ALERT pin can be connected as an SMBus alert signal. When a master senses that an ALERT
condition is present on the ALERT line, the master sends an SMBus alert command (0001 1001) to the bus. If
the ALERT pin is active, the device acknowledges the SMBus alert command and responds by returning the
slave address on the SDA line. The eighth bit (LSB) of the slave address byte indicates if the ALERT condition
was caused by the temperature exceeding THIGH or falling below TLOW. For POL = 0, the LSB is low if the
temperature is greater than or equal to THIGH; this bit is high if the temperature is less than TLOW. The polarity of
this bit is inverted if POL = 1. See Figure 10 for details of this sequence.
If multiple devices on the bus respond to the SMBus alert command, arbitration during the slave address portion
of the SMBus alert command determines which device clears the ALERT status. The device with the lowest two-
wire address wins the arbitration. If the TMP102 device wins the arbitration, its ALERT pin inactivates at the
completion of the SMBus alert command. If the TMP102 device loses the arbitration, its ALERT pin remains
active.
