摘要： A communication channel is operated by storing a calibrated parameter value in nonvolatile memory during manufacturing, testing, or during a first operation of the device. Upon starting operation of the communication channel in the field, the calibrated parameter value is obtained from the nonvolatile memory, and used in applying an operating parameter of the communication channel. After applying the operating parameter, communication is initiated on a communication channel. The operating parameter can be adjusted to account for drift immediately after starting up, or periodically. The process of starting operation in the field includes power up events after a power management operation. In embodiments where one component includes memory, steps can be taken prior to a power management operation using the communication channel, such as transferring calibration patterns to be used in calibration procedures.

摘要： An integrated circuit is described. The integrated circuit includes an interface circuit that includes a transmitter and a receiver. A generator in the integrated circuit is selectively coupled to the transmitter. The generator is to provide a test sequence that is output by the transmitter during a test mode of operation. A memory in the integrated circuit is selectively coupled to the generator and the receiver. The memory is to receive and synchronize the test sequence and a signal corresponding to the test sequence that is received by the receiver. A logic circuit in the integrated circuit is to compare the test sequence and the signal.
