Description
PowerOnToPowerGoodTime: This byte specifies the duration HCD must
wait before accessing a powered-on port of the root hub. It is implementation
specific. The unit of time is 2 ms. The duration is calculated as POTPGT ×
2 ms.
reserved
NoOverCurrentProtection: This bit describes how the overcurrent status
for root hub ports are reported. When this bit is cleared, the
OverCurrentProtectionMode (OCPM) field specifies global or per-port
reporting.
0 — overcurrent status is collectively reported for all downstream ports.
1 — no overcurrent reporting supported.
OverCurrentProtectionMode: This bit describes how the overcurrent status
for root hub ports are reported. At reset, this field should reflect the same
mode as PowerSwitchingMode. This field is valid only if the
NoOverCurrentProtection (NOCP) field is cleared.
0 — overcurrent status is collectively reported for all downstream ports.
1 — overcurrent status is reported on a per-port basis. On power up, clear
this bit and then set it to logic 1.
DeviceType: This bit specifies that the root hub is not a compound device; it
is not permitted. This field should always read as 0.
NoPowerSwitching: This bit is used to specify whether power switching is
supported or ports are always powered. It is implementation specific. When
this bit is cleared, the PowerSwitchingMode (PSM) bit specifies global or
per-port switching.
0 — Ports are power switched.
1 — Ports are always powered on when the host controller is powered on.
