ABSTRACT:
A communication terminal in which the power consumption in an intermittent reception state can be reduced significantly. The state value of a second spread code generating circuit (62) for a next drive is set in a register (73) to operate a timer (70), and the first and second spread code generating circuit (62, 75) and the receiving circuit are stopped and put in a sleep state. Then, if they are driven again by the timeout of the timer, the receiving circuit is operated and the second spread code generating circuit is operated from the state value which has been set in the register. Further, the intermittent receiving circuit (65) for operating the first spread code generating circuit from an initial state is provided. Therefore, in non-reception, the first and second spread code generating means can be stopped, so that the power consumption in an intermittent state can be reduced significantly.
