Abstract

PURPOSE: To test an I/O control device under the state most similar to the connection to the actual I/O device, by constituting a test generating device by the control circuit which accesses the ROM or the RAM.
CONSTITUTION: Test signal generating device 2 which tests I/O control device 1 is connected to I/O control device 1, and this generating device is provided with bit pattern storage ROM5 to store the bit pattern for test signal and ROM address counter 6 to designate the read address of ROM5. Further, clock generating circuit 7 which generates clocks to read the bit pattern and control circuit 4 which controls the read of the bit pattern are provided. Then, the bit pattern read from ROM5 is applied to I/O control device 1 in serial through interface circuit 3, and thus, I/O control device 1 is tested under the nearest state to connection to the actual I/O device.
