The Device Select sub-tab allows the user to choose the device on the l-Wire~ bus which it will communicate to and demonstrates the SWAP feature of the DS2720. Clicking on the Find DS2720 Net Address button will begin a SEARCH NET ADDRESS operation on the l-Wire bus. All DS2720s found on the bus will be listed in the Net Addresses field. To communicate to any device on the bus, click on its address inside the Net Addresses field to select it. The program will now use this device for all operations until a different DS2 720 is chosen. Clicking on the Swap to Selected DS2 720 button will demonstrate the features of the SWAP command provided all DS2720s on the bus have both PMOD and SWEN bits enabled in their status registers. Issuing the SWAP command will cause the selected DS2720 to wake up and enable its control FETs while simultaneously all other devices disable their control FETs and enter sleep mode. To disable all available 2720s select the Anonymous Net Address and SWAP to it.
