Description
PowerOnToPowerGoodTime: This byte specifies the duration
HCD has to wait before accessing a powered-on port of the Root
Hub. 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 field specifies
global or per-port reporting.
0 — overcurrent status is reported collectively for all downstream
ports
1 — no overcurrent reporting supported
OverCurrentProtectionMode: This bit describes how the
overcurrent status for the Root Hub ports is reported. At reset, this
field reflects the same mode as PowerSwitchingMode. This field is
valid only if the NoOverCurrentProtection 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 will always
read/write 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 bit
PowerSwitchingMode specifies global or per-port switching.
0 — ports are power switched
1 — ports are always powered on when the HC is powered on
PowerSwitchingMode: This bit is used to specify how the power
switching of the Root Hub ports is controlled. It is
implementation-specific. This field is valid only if the
NoPowerSwitching field is cleared.
0 — all ports are powered at the same time
1 — each port is powered individually. This mode allows port
power to be controlled by either the global switch or per-port
switching. If bit PortPowerControlMask is set, the port responds to
only port power commands (Set/ClearPortPower). If the port mask
is cleared, then the port is controlled only by the global power
switch (Set/ClearGlobalPower).
reserved
NumberDownstreamPorts: These bits specify the number of
downstream ports supported by the Root Hub. The maximum
number of ports supported by the ISP1161A1 is 2.
