Description
POTPGT[7:0]
PowerOnToPowerGoodTime:
This byte specifies the
duration HCD has to 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
NOCP
NoOverCurrentProtection:
This bit describes how the
overcurrent status for Root Hub ports are reported. When this
bit is cleared, the OCPM (OverCurrentProtectionMode) field
specifies global or per-port reporting.
23 to 13
12
0 —
overcurrent status is reported collectively for all
downstream ports
1 —
no overcurrent protection supported
OverCurrentProtectionMode
: This bit describes how the
overcurrent status for Root Hub ports are reported. At reset,
this fields reflects the same mode as PowerSwitchingMode.
This field is valid only if the NOCP field is cleared.
11
OCPM
0 —
overcurrent status is reported collectively for all
downstream ports
1 —
overcurrent status is reported on a per-port basis
DeviceType
: This bit specifies that the Root Hub is not a
compound device. The Root Hub is not permitted to be a
compound device. This field should always read 0.
