DEFINITION

Classification: 326/37

MULTIFUNCTIONAL OR PROGRAMMABLE (E.G., UNIVERSAL, ETC.):

(under the class definition) Subject matter including (a) a logic circuit capable of either producing different logic function operations from the same logic element or providing a particular, selected (i.e., programmed) logic operation from plural logic elements (e.g., an array, etc.) or (b) details related to the actual setting or programming of the desired logic functions in such a logic circuit.

(1) Note. A multifunctional logic element is, for example, a single element capable of being changed by a control signal from an "AND" to a "NOT" logic function.
