EM_CTL—Enclosure Management Control Register (D31:F2)
Address Offset: ABAR + 20h–23h
Default Value:
This register is used to control and obtain status for the enclosure management
interface. This register includes information on the attributes of the implementation,
enclosure management messages supported, the status of the interface, whether any
message are pending, and is used to initiate sending messages. This register is
reserved if enclosure management is not supported (CAP_EMS = ‘0’).

Activity LED Hardware Driven (ATTR.ALHD) — R/WO.
1 = The SATA controller drives the activity LED for the LED message type in hardware
The host controller does not begin transmitting the hardware based activity signal until after
software has written CTL.TM=1 after a reset condition.
Transmit Only (ATTR.XMT) — RO.
0 = The SATA controller supports transmitting and receiving messages.
1 = The SATA controller only supports transmitting messages and does not support
Single Message Buffer (ATTR.SMB) — RO.
0 = There are separate receive and transmit buffers such that unsolicited messages
1 = The SATA controller has one message buffer that is shared for messages to
