CONSTITUTION:In the case of initializing processing, a CPU 7 judges the matching of ID data stored in a RAM 9 by collating a write number stored in the managing area in an ID-ROM 5 with a check sum and when those data are matched with each other, ID information is read out from the ID data stored in the RAM 9 and set it to a decoder part 4 but, and those data are not matched with each other, the write number stored in the ID-ROM 5 and the ID data are read out and set them to the RAM 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a setting device for setting a reception control function in a receiving device represented by a paging receiver.

[0002]

2. Description of the Related Art Recently, pagers are cheaper to use than car phones and mobile phones, so not only companies have them for phone calls from outside offices but also friends who are out and about. The number of cases where it is used as an easy communication tool with is rapidly increasing. As a conventional access method to a pager, there is a telephone for an individual, a company, and an operation service company, a personal computer input, an information processing company, etc. for an individual information provider.

The information created by these access means is sent to the pager service company via the public line network, and the pager service company creates and sends the send information for each page number of the pager owned by the individual or the company. It The pager includes an NP (Numeric Pager) type capable of receiving numerical information and an IP (Information Pager) type capable of receiving character information.

In these pagers, the information peculiar to the terminal is usually stored in advance in a non-volatile ROM called an ID-ROM and mounted on each terminal, but it has a receiving function for receiving various information services. As the pager becomes more sophisticated, the chances of changing the content of information stored in the ID-ROM tend to increase. Therefore, the ID
A non-volatile, electrically rewritable EEPROM is used as the ROM, which is very useful in procedures for new subscription such as service information using the pager service.

[0005]

However, in such a conventional pager, as an ID-ROM for storing the information peculiar to the terminal for the above reasons,
Non-volatile but electrically rewritable EEPR
Although the OM is used, this EEPROM has the following problems because it takes time to read data. That is, conventionally, the process of reading information from the ID-ROM and the process of writing the read information to the RAM are performed as the setting process when the power of the pager is turned on. At this time, all the information is read from the ID-ROM. If so, the initial operation takes too much time because the EEPROM read speed is slow, so only some information is read when the power is turned on, and all information is read when the power is turned on for the first time after battery replacement. It was done with all clear. For this reason, when the ID-ROM is rewritten, there is a problem that the information stored in the RAM cannot be confirmed unless the all-clear operation is performed without preventing the accident due to the garbled data. .

An object of the present invention is to provide an ID in a setting process performed at power-on in a receiver such as a pager.
-Check whether the information stored in the ROM is updated or not.
It is an object of the present invention to provide a setting device for controlling a setting process by writing information to a RAM after making a judgment by collating with the information stored in AM.
