PortResetStatusChange: This bit is set at the end of the 10 ms
port reset signal. The HCD writes a logic 1 to clear this bit. Writing
a logic 0 has no effect.
0 — port reset is not complete
1 — port reset is complete
19
OCIC
PortOverCurrentIndicatorChange: This bit is valid only if
overcurrent conditions are reported on a per-port basis. This bit is
set when Root Hub changes the PortOverCurrentIndicator bit. The
HCD writes a logic 1 to clear this bit. Writing a logic 0 has no
effect.
0 — no change in PortOverCurrentIndicator
1 — PortOverCurrentIndicator has changed
18
PSSC
PortSuspendStatusChange: This bit is set when the full resume
sequence has been completed. This sequence includes the 20 s
resume pulse, LS EOP, and 3 ms re-synchronization delay. The
HCD writes a logic 1 to clear this bit. Writing a logic 0 has no
effect. This bit is also cleared when ResetStatusChange is set.
0 — resume is not completed
1 — resume is completed
