Table 6-5 Port LRAM Slot layout
A Port LRAM Slot is 128 bytes used to define Serial-ATA commands. The addresses shown above are for slot 0.
6.3.1.1 Command Activation Register
The Command Activation Register is written using a shadow address. The Command Execution State Machine overwrites it
when the Scatter/Gather Table is fetched. The translation of the shadow address to the actual LRAM address is shown here:

6.3.1.2 Port Multiplier Device Specific Registers
The Port Multiplier Device Specific Registers are 16 registers that contain the SActive register and the Diagnostic register for
each of the 16 devices that may be connected to a Port Multiplier. Besides being directly addressable in the LRAM address
space, the currently selected Port Multiplier Port SActive register may be indirectly addressed at offset 1F0C

address for this indirect (read-only) access is derived as shown here:
