One embodiment of the present invention is a programmable clock architecture for a microcontroller that provides multiple different clocking signal frequencies that may be utilized by one or more programmable logic blocks of the microcontroller. The device housing can be formed of a thermoplastic, or a metal such as aluminum or stainless steel. Then, depending on the passage of a predetermined time, the process of releasing a data link is started. may be a reflection diffracted from the material, or a reflection.
