Description
PowerOnToPowerGoodTime: This byte specifies the duration HCD
has to wait before accessing a powered-on port of the Root Hub. It is
implementation-specific (IS). The unit of time is 2 ms. The duration is
calculated as POTPGT
reserved
NoOverCurrentProtection: This bit describes how the overcurrent
status for the 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 the 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 reported collectively 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 HC is powered on
