Slot Status (SLSTS) – Offset 5A
Slot Status
Bit Range | Default | Access | Field Name and Description |
---|---|---|---|
15:9 | 0x0 | RO | Reserved (RSVD_M) Reserved. |
8 | 0x0 | RW/1C/V | Data Link Layer State Changed (DLLSC) This bit is set when the value reported in Data Link Layer Link Active field of the Link Status register is changed. In response to a Data Link Layer State Changed event, software must read Data Link Layer Link Active field of the Link Status register to determine if the link is active before initiating configuration cycles to the hot plugged device. |
7 | 0x0 | RO | Electromechanical Interlock Status (EMIS) Reserved as this port does not support and electromechanical interlock. |
6 | 0x0 | RO/V | Presence Detect State (PDS) If XCAP.SI is set (indicating that this root port spawns a slot), then this bit indicates whether a device is connected ('1') or empty ('0'). If XCAP.SI is cleared, this bit is a '1'. |
5 | 0x0 | RO | MRL Sensor State (MS) Reserved as the MRL sensor is not implemented. |
4 | 0x0 | RO | Command Completed (CC) This register is RO as this port does not implement a Hot Plug Controller.. |
3 | 0x0 | RW/1C/V | Presence Detect Changed (PDC) This bit is set by the root port when the PD bit changes state. |
2 | 0x0 | RO | MRL Sensor Changed (MSC) Reserved as the MRL sensor is not implemented. |
1 | 0x0 | RO | Power Fault Detected (PFD) Reserved as a power controller is not implemented. |
0 | 0x0 | RO | Attention Button Pressed (ABP) This register is RO as this port does not implement an attention button. |
