11.8.3 Overcurrent detection circuit using internal charge pump in OTG mode
When port 1 is operating in OTG mode, you may choose to use the internal charge pump
to provide 5 V V
condition is detected by a drop in V
overcurrent condition causes a change in the A_VBUS_VLD bit of the OtgStatus register.
The software must clear the DRV_VBUS bit in the OtgControl register when it detects the
A_VBUS_VLD bit turning to logic 0.
