APPLICATION INFORMATION
Table 4. Page 0 (Port Status) Register Field Descriptions (Continued)
FIELD SIZE TYPE DESCRIPTION
PIE 1 Rd/Wr Port event interrupt enable. When set to 1, a port event on the selected port sets the port event interrupt (PEI) bit
and notify the link. This bit is reset to 0 by hardware reset and is unaffected by bus-reset.
Fault 1 Rd/Wr Fault. This bit indicates that a resume-fault or suspend-fault has occurred on the selected port and that the port is in
the suspended state. A resume-fault occurs when a resuming port fails to detect incoming cable bias from its
attached peer. A suspend-fault occurs when a suspending port continues to detect incoming cable bias from its
attached peer. Writing 1 to this bit clears the Fault bit to 0. This bit is reset to 0 by hardware reset and is unaffected
by bus-reset.
The vendor identification page is used to identify the vendor/manufacturer and compliance level. The page is
