Serializer/deserializer and method for transferring data between an integrated circuit and a test interface

Abstract

A serializer/deserializer for communicating with an integrated circuit. The serializer/deserializer includes a serializer configured to serialize, from a parallel format into a serial format, first data to be transferred from an external device to the integrated circuit. The external device is configured to perform testing on the integrated circuit. A deserializer is configured to deserialize, from the serial format into the parallel format, second data to be transferred from the integrated circuit to the external device. A test access port module is configured to receive, from a test interface arranged between the serializer/deserializer and the external device, third data for controlling the serializer and provide, to the test interface, fourth data associated with control of the test interface. The fourth data corresponds to the deserialization of the second data to be transferred from the integrated circuit to the external device.
