A PLL control circuit, which outputs a PLL clock in response to a reference clock, is provided with a frequency adjustment circuit which performs frequency adjustment such that the PLL clock frequency is substantially constant even when the reference clock varies. The frequency adjustment circuit changes a set value in a counter, which determines the PLL clock frequency, in accordance with the variation in the reference clock frequency.

A method of setting up a pointing device on a portable terminal according to the present invention has a first step for moving a user icon on a display unit of the portable terminal by the pointing device to follow a target icon, and a second step for acquiring parameters associated with the pointing device based on user icon movement information generated by the first step.

A radio selective-calling receiver that defers indication of receipt of a call for the receiver until after a further frame when the further frame is also for the receiver. A data separating section takes in demodulated signals by sampling. When the receiver's calling number exists in the received data, a controller waits until the next frame that is also an &ldquo;own&rdquo; frame, to output display signals or sound signals. Therefore, at the time when the own address is being received, the informing operation can be prevented and the receiving operation can be implemented in a more stable receiving state. As a result, the deterioration of the receiving sensitivity is prevented and the effect that the error of the receiving data is decreased can be obtained.
