8.3.3.2.1.2 Last Device Poll

When the host issues a last-device-poll command, the last sensor on the initialized daisy chain responds back with the last device address, as shown in Figure 24. The last-device-poll command is also used to check if the daisy-chain address set is intact. If the daisy chain is not intact, the host does not receive a response to the last-device-poll command. This command only works if the last device in the chain was the last device during initialization. For example, if there are ten devices in the chain during address initialization and two devices are removed, running this command does not provide the host with the address of device eight. Device eight was not the last device during chain initialization, so it cannot report that device eight is the last device in the chain. In this example, the command is not answered.
