Using the TRF7970A EVM With PC GUI
2.3.6 Write Multiple Blocks (Command Code 0x24)
This optional command is not currently known to be supported by any ISO/IEC 15693 transponders
available.
2.3.7 Stay Quiet (Command Code 0x02)
The Stay Quiet command is a mandatory command which instructs the VICC to enter the quiet state. The
command is always issued as an addressed command and of course there is no response to the Stay
Quiet Command. The VICC exits the quiet state when the transponder exits the field, receives a Reset to
Ready command or a Select request.
To perform Stay Quiet command using the GUI:
1. Perform Inventory command (see Section 2.3.1) to obtain UID of VICC
2. Leave tag/transponder in field
3. Select the radio button for Stay Quiet
4. Select Tag Flags accordingly (see Figure 11 for one example)
5. Click Set Protocol. (if Data Rate or Sub-carrier Tag Request Flags are changed)
6. Click Execute
