R Over Current Indicator
This bit reports the over-current condition. When this bit is
set, an over-current condition exists. When this bit is
cleared, all power operations are normal. This bit is always
0 when the over-current protection at each port is carried
out.
0: All power operations are normal
1: An over-current condition exists

R/W (Read) Local Power Status
The root hub does not support the local power status
function. Therefore, the bit is always read 0.
(Write) Clear Global Power
This bit is written to 1 to power on (the PPS bit in
USBHRPS is cleared) all ports in global power mode
(PSM in USBHRDA = 0).
In the power mode at each port, the PPS bit is cleared to
the port in which the PPCM bit is not set. Writing a 0 has
no effect.
