RF_INTERRUPT:

•

A pulse is emitted on GPO by Manage GPO command (interrupt).

•

When RF_INTERRUPT is activated, a pulse of duration IT_TIME is emitted after EOF of ST25DVxxKC

response to a Manage GPO interrupt command (see Section 7.6.30 Manage GPO).

3) VCD sends a ManageGPO command (any value) and ST25DVxxKC stays quiet (command not for

this VICC, or quiet state). GPO/RF_INTERRUPT remains high-Z.
