7.3.2.2 Serial Bus Address

To communicate with the TMP112-Q1/TMP112D-Q1 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-Q1/TMP112D-Q1 device features an address pin to allow up to four devices to be addressed on a single bus. Table 7-4 lists the pin logic levels used to properly connect up to four devices.
