The address byte consists of seven address bits and a read-write (R/W) bit indicating the intent of executing a read or write operation. The TMP116 features an address pin to allow up to four devices to be addressed on a single bus. Table 2 describes the pin logic levels used to properly connect up to four devices. x represents the read-write (R/W) bit. Table 2. Address Pin and Slave Addresses DEVICE TWO-WIRE ADDRESS ADD0 PIN CONNECTION 1001000x Ground 1001001x V+ 1001010x SDA 1001011x SCL 7.5.3.1.3 Writing and Reading Operation Accessing a particular register on the TMP116 is accomplished by writing the register address 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 TMP116 requires a value for the pointer register. When reading from the TMP116, the last value stored in the pointer register by a write operation is used to determine 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 an address byte with the R/W bit low, followed by the pointer register byte. No additional data are required. The master can then generate a START condition and send the slave address byte with the R/W bit high to initiate the read command; see Figure 28 for details of this sequence. If repeated reads from the same register are desired, continuously sending the pointer register bytes is not necessary because the TMP116 retains the pointer register value until the value is changed by the next write operation. Register bytes are sent with the most significant byte first, followed by the least significant byte. 7.5.3.1.4 Slave Mode Operations The TMP116 can operate as a slave receiver or slave transmitter. As a slave device, the TMP116 never drives the SCL line. 7.5.3.1.4.1 Slave Receiver Mode The first byte transmitted by the master is the slave address with the R/W bit low. The TMP116 then acknowledges reception of a valid address. The next byte transmitted by the master is the pointer register. The TMP116 then acknowledges reception of the pointer register byte. The next byte or bytes are written to the register addressed by the pointer register. The TMP116 acknowledges reception of each data byte. The master can terminate data transfer by generating a START or STOP condition. 7.5.3.1.4.2 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 can terminate data transfer by generating a not-acknowledge on reception of any data byte or by generating a START or STOP condition. |
