USB ULPI VBUS Control (ULPIVBUSCTL)
OTG A / Host
OTG B / Device
ULPI PHYs may use an external charge pump to generate VBUS rather than an internal charge pump. This register allows selection of the external charge pump. It also allows this selection to be displayed through the external USB0VBUS signal.
NOTE
This register is read back from the PHY clock domain. These bits will not therefore return updated values while the PHY is suspended.
ULPIVBUSCTL is shown in Figure 27-22 and described in Table 27-27.
