Description
Power Switching Mode
This bit specifies the root hub port power switching
control method. It is implementation specific. This bit
is valid only when the NPS bit is cleared to 0.
0: All ports are powered at the same time.
1: Each port is powered individually. This mode
Number of Downstream Ports
These bits specify the number of downstream ports
supported by the root hub. It is implementation-
specific. The value of these bits is H'2. However,
this LSI supports only 1 port for downstream.
R/W
R/W
allows port power to be controlled by either the
global switch or per-port switching. When
HcRhDescriptorB.PPCM = H'0002, the port
responds only to port power commands
(Set/ClearPortPower). When the port mask is
cleared, then the port is controlled only by the
global power switch (Set/ClearGlobalPower).
