DEFINITION

Classification: 713/501

Multiple or variable intervals or frequencies:

(under subclass 500) Subject matter including generation and selection of plural or variable timing intervals.

(1) Note. This subclass accepts selecting or programming a clock rate in a computer or digital data processing system. Setting system initial operating parameters through a booting process is classified elsewhere.
