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.

End of line effect can occur during manufacture of components using a lithographic apparatus. These end of line effects can result in line end shortening of the features being manufactured. Such line end shortening may have an adverse impact on the component being manufactured. It is therefore desirable to predict and / or monitor the line end shortening. A test pattern is provided that has two separate areas such that, as designed, when the two areas are illuminated with radiation (for example from an angle-resolved scatterometer) they result in diffused radiation with asymmetry that is equal in sign to each other, but opposite in magnitude. When the test pattern is actually manufactured, line end shortening occurs, and so the asymmetry of the two areas are not equal and opposite. From the measured asymmetry of the manufactured test pattern, the amount of line end shortening that has occurred can be estimated.
