Oscillation control apparatus for a portable battery-driven terminal

摘要

A novel terminal apparatus of low power consumption type is disclosed, in which an oscillation circuit is controlled to be energized only when a CPU is operated and de-energized otherwise, thus remarkably reducing power consumption. The progress of the CPU technology has made it possible to stop oscillation temporarily without sacrificing the CPU operation, unlike the conventional CPU circuit whose operation cannot be assured without constant application of an oscillation frequency thereto.
