摘要： Disclosed is a scan apparatus (4) which provides an interface and control signals between a secondary computer (1) and data locations in a host computer (2). The scan apparatus (4) functions independently of the normal operation of the host computer (2). Scan-out is performed transparently to the operation of the host computer (2). The host computer (2) is constructed using circuits on semiconductor chips (7-1, 7-Y). The semiconductor chips (7-1, 7-Y) are organized in blocks (3-1). Chips within each block (3-1) include scan apparatus (4) which controls the scan operations in connection with that chip. The scan apparatus in each chip is connected through two I/O pins to a clock lines and to a bidirectional scan data line. The scan apparatus on each chip includes a multimode sequencer so that each chip in each block can be independently performing scan sequences. The block scan apparatus and the secondary computer perform the functions of requesting a scan sequence for transmitting the scan data.
