one. This bit is set to one by the Global reset, which is set by a PCI reset, and remains set until cleared by the
host (by writing a one to bit 0 of the Port Control Clear register).
The register bits that are not initialized by the Port Reset are:
OOB Bypass (bit 25) in Port Control (this register)
Port PHY Configuration register (all bits)

This register is used to determine the status of various port functions.
Bit [31]
: Port Ready (R). This bit reports the Port Ready status. The transition from 0 to 1 of this bit generates
the Port Ready Interrupt Status (bit 18/2 of the Port Interrupt Status register).
Bit [30:26,24:21]
: Reserved (R). These bits are reserved.
Bit [20:16]
: Active Slot (R). This bit field contains the slot number of the command currently being executed.
When a command error occurs, this bit field indicates the slot containing the command in error.
Bit [25,15:0]
: These bits reflect the current state of the corresponding bits in the Port Control register. Refer to
the Port Control Set register for a complete description.

This register is used to direct various port operations. A one written to a bit position clears that bit in the control register.
Bit [31:26,24:16,12:11,6,2:1]
: Reserved (R). These bits are reserved.
Bit [25,15:13,10:7,5:3,0]
: (W1C) Writing a one to these bits clears the associated bit position of the Port Control
register. Refer to the Port Control Set register for bit descriptions.
