USB Port Power
Control 2
PRTCTL2
IS/OD12
(PU)
When used as an output, this pin enables power to
downstream USB peripheral 2.
When used as an input, this pin is used to sample
the output signal from an external current monitor
for downstream USB peripheral 2. An overcurrent
condition is indicated when the signal is low.
Refer to Section 2.2 for additional information.
