Abstract
A communication module includes a switch circuit operable to connect an internal bus to an external bus for, e.g., diagnostics, verification, and fault analysis. The internal bus allows data communication between electronic components internal to the communication module, and the external bus allows data communication between at least one internal electronic component and a device external to the communication module. The switch circuit may be controlled via a programmable and password protected register within the communication module.
