Abstract
A circuit arrangement for a mobile telephone comprises a microprocessor responsive to a clock signal for controlling its functions, and a signalling circuit, e.g. a modem which is coupled to the microprocessor to provide an output clock signal thereto. In the idle states of the processor, the output clock signal is stopped, using a stop signal from the microprocessor. This gives use to reduce power consumption and a consequential increase in battery life.
