ATA interface connects each disc drive in a point to point configuration with the Serial ATA host adapter There is no master slave relationship with Serial ATA devices like there is with parallel ATA If two drives are attached on one Serial ATA host adapter the host operating system views the two devices as if they were both masters on two separate ports This essentially means both drives behave as if they are Device 0 master devices Note The host adapter may optionally emulate a master slave environment to host software where two devices on separate Serial ATA ports are represented to host software as a Device 0 master and Device 1 slave accessed at the same set of host bus addresses A host adapter that emulates a master slave environment manages two sets of shadow registers This is not a typical Serial ATA environment The Serial ATA host adapter and drive share the function of emulating parallel ATA device behavior to provide backward compatibility with existing host systems and software The Command and Control Block registers PIO and DMA data transfers resets and interrupts are all emulated The Serial ATA host adapter contains a set of registers that shadow the contents of the traditional device regis ters referred to as the Shadow Register Block All Serial ATA devices behave like Device 0 devices For addi tional information about how Serial ATA emulates parallel ATA refer to the Serial ATA High Speed Serialized A
