  • Multimode data system for transferring control and data information in an I/O subsystem
    Patent number: 5097410
    Abstract: A system structured to transfer control information between an IFA (I/O interface adapter) and an I/O processor, and I/O data between an IFA and a CDB (channel data buffer) has separate interfaces for these transfers. The control interface includes a multi-mode, bidirectional control data bus, a control mode bus for establishing the mode of the bus, and a check interface on which the IFA provides error information. The data interface includes a multi-mode, bidirectional data transfer bus, respective SYNC and ACCEPT lines for transferring time-phased control signals to establish the mode of the data transfer bus, and a parity line to indicate to the IFA the parity of the SYNC and ACCEPT lines.
