ABSTRACT:
An integrated circuit for a smart card may include a transceiver for communicating with a host device and a Joint Test Action Group (JTAG) test controller for performing at least one test operation. Further, the integrated circuit may also include a processor for causing the JTAG test controller to initiate the at least one test operation based upon receiving at least one test request from the host device via the transceiver. More particularly, the processor may convert the at least one test request to JTAG data for the JTAG test controller. That is, the integrated circuit advantageously allows communications between the host device and the JTAG controller via a system bus, for example, without the need for a dedicated JTAG test access port (TAP) which is typically required for accessing JTAG controllers.
