Abstract:
1. A system for emulating a serial small computer system interface (serial SCSI) connection for direct attached serial advanced technology attachment (serial ATA) communication, comprising: a host controller including a first physical interface configured to connect with a serial SCSI device and a second physical interface configured to connect with a serial ATA device, the host controller including: wherein the emulation logic generates at least one of asserting a ConnectedSata signal or deasserting a ConnectedSata signal based on the state of a host link state machine, the emulation logic being configured for accounting for a status of registers of a Phy layer and accounting for a status of registers of a port layer to an extent that data contained in the registers of the Phy layer and the port layer indicate conditions impacting the connection emulation.
