To communicate with the device, the controller must first address target devices through a target-address byte. The target-address byte consists of seven address bits and a direction bit indicating the intent of executing a read or write operation.
The TMP112 family features an address pin to allow up to four devices to be addressed on a single bus. Table 7-4 describes the pin logic levels used to properly connect up to four devices. This table also describes four different address options available when ALERT pin is used in TMP112Dx.
