V850ES/JG3-U, V850ES/JH3-U
21.3.3 USB power supply

(1) Overcurrent detection and power control
(2) VBUS control specification according to root hub register setting conditions
The V850ES/JG3-U and V850ES/JH3-U do not have a circuit for detecting overcurrent or controlling power to the
USB port.
To support these functions in the system, use an external circuit such as a USB high-side switch to configure these
functions and connect it with the OCI and PPON pins.
The following table shows the operations related to the OCI and PPON pins used for controlling the external circuit
for detecting overcurrent or controlling power to the USB port.
Figure 21-5 shows a connection example for overcurrent detection and power (VBUS) control. When the USB bus
is not used, power consumption can be reduced by stopping VBUS supply to the port, though its availability
depends on the connection to the USB connector. If the connected USB function device is buspowered, it is
recommended to use a high-side switch as shown in the connection example.
Control of the PPS bit for controlling VBUS varies depending on the setting of the HcRhDescriptorA and
HcRhDescriptorB (Root Hub control) registers.
When controlling VBUS for each port, the HcRhDescriptorA.NPS and HcRhDescriptorA.PSM bits must be set to “1”.
