Description
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
(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.
