Using the TRF7970A EVM With PC GUI
2.4.2 Select, RATS, and PPS
The Select command radio button is automatically selected after the anticollision loop is complete when
using the ISO14443A tab, because this command cannot be issued to a PICC until the UID is obtained.
To issue Select command, leave the PICC in the field and click Execute (see Figure 22).
Figure 22. Select Command Example
After the Select command request is sent and a valid response is obtained, the GUI automatically selects
the RATS radio button. The user again only needs to select the Execute button to process the command
request (see Figure 23). Then the PPS radio button is automatically selected and is available as example,
but the PICC must support it.
