Method of forming a semiconductor device and structure therefor

摘要

In one embodiment, a semiconductor device may include a controller that may be configured to receive an information signal from a detachable device wherein the information signal may be selectively representative of an output signal of the controller according to codes of the detachable device and to receive a sense input that may be representative of the output signal and to determine a code received from the detachable device according to a value of the sense signal and the information signal.

主权项

1. A semiconductor device configured for identification of a detachable device, comprising:
a controller configured to control one or more output signals to excite the detachable device; one or more information inputs of the controller configured to receive one or more information signals from the detachable device wherein the one or more information signals are selectively representative of the one or more output signals according to codes of the detachable device; and one or more sense inputs of the controller configured to receive one or more sense signals that are representative of the one or more output signals wherein the controller is configured to determine the codes according to values of the one or more sense signals and the one or more information signals.
