Using the TRF7970A EVM With PC GUI
www.ti.com
2.3 ISO15693 Tab
By default the TRF7970A EVM GUI starts up with the ISO15693 tab selected. The user should set/select
the transponder/tag request flags as appropriate for the given operation (details on this to follow for each
command) and by using the Set Protocol button in the GUI first before executing any commands so that
the TRF7970A register settings match what is being sent out/expected back to/from the transponder(s) in
the field of the EVM antenna. Please note that there are only two mandatory commands in ISO/IEC 15693
standard (Inventory and Stay Quiet). All other available commands are either Optional (as defined by the
ISO/IEC 15693 standard) or Custom (as defined by the transponder IC manufacturer by means of the
framework outlined in ISO/IEC 15693 standard). The user should always use the transponder/tag IC
specific data sheet in conjunction with this guide to ensure settings and commands match what the
transponder is designed to support. To avoid any misunderstanding regarding the transponder/tag request
flags, see Table 3, Table 4, and Table 5 (taken from the ISO/IEC 15693-3 standard).
