CLOCK CONTROL OF DATA PROCESSING SYSTEM, COMPONENT, OR DATATRANSMISSION:
(under the class definition) Subject matter wherein there is a significant temporal, incremental, or sequencing control provided to a digital data processing system, processor, memory or peripheral, or to data transmission between such systems or components.
(1) Note. This is a generic subclass for clock control of operations of digital data processing systems or components thereof and for timing and clock related control of movement of data between systems or components.
(2) Note. Nominally claimed clock control of apparatus external to this class in combination with apparatus under this subclass definition is classified in this subclass unless provided for in the appropriate external class.
(3) Note. Significantly claimed clock control of apparatus external to this class in combination with apparatus under this subclass definition, which perform data processing or transmission operations, is classified in the class appropriate to the external device unless specifically excluded therefrom.
