Description
NoPowerSwitching (NPS)
This bit selects whether the power switching is supported or
ports are always power-supplied. This bit is implementation
specific. When this bit is cleared, Power-SwitchingMode
specifies the global/port switching.
0: Ports can be power-switched.
1: Ports are always powered on when the host controller is
Note: Because the initial value is 1, first clear this bit (write 0
PowerSwitchingMode (PSM)
This bit specifies how the power switching of the root-hub port is
controlled. This bit is implementation specific. This bit is valid
only when the NoPowerSwitching bit is cleared.
0: All ports are simultaneously power-supplied. (initial value)
1: Each port is power-supplied individually. In this mode, the
NumberDownstreamPorts (NDP)
These bits specify the number of downstream ports supported
by the root hub. These bits are implementation specific.
In the SH7727 their value is H'2.
powered on. (initial value)
port power is controlled with either of global/port switching.
When the PortPowerControlMask bit is set, the port is
reacted only to the port-power command (set/clear port
power). When the port mask is cleared, the port is controlled
only by the global power-switch (set/clear global power).
with the HCD) to enable power switching of the port.
