PROBLEM TO BE SOLVED: To provide a data radio equipment coping with computer connection for which the operating speed when a computer is connected, is accelerated within a range of not deteriorating error rate at the time of reception and the power consumption is reduced. SOLUTION: Signals to a RAM 23 are supplied from a high driving ability output buffer 25 when the computer 21 is connected, a low driving ability output butter 26 is selected when the computer 21 is not connected and thus, the power consumption is reduced. Also, When the computer 21 is connected, a frequency division number in a counter circuit 18 is changed corresponding to the error generation conditions of reception data and the operating speed of a central processing unit 15 is changed. Thus, the response to the computer 21 is improved within a range of not deteriorating the error rate. |
