ID NUMBER RETRIEVAL METHOD IN CORDLESS TELEPHONE

摘要

This method reconstructs an unique ID number by restoring it in EEPROM in three parts. ID number registered in EEPROM in three parts when the user changes wireless telephone mode to ID registering mode and inputs the unique ID number. When the potable equipment powered on, RAM reads the ID number in the three parts of EEPROM sequentially and compares the first number with the second number. If these two numbers are the same, RAM compares the second number with the third number. When these two numbers are the same, RAM extracts this number and waits for communication.
