... DESCRIPTION The Teridian 73S8024RN is a single smart card (ICC) interface IC that can be controlled by a dedicated control bus. The 73S8024RN has been designed to provide full electrical compliance with ISO-7816-3, EMV 4.0 (EMV2000) and NDS specifications. Interfacing with the system controller is done through a control bus, composed of digital inputs to control the interface, and one interrupt output to inform the system controller of the card presence and faults ...

... No card in the reader). When CMDVCC is set low (Card activation sequence requested from the host), low level on OFF means a fault has been detected (e.g. card removal during card session, or voltage fault, or thermal / over-current fault) that automatically initiates a deactivation sequence.
