2.4.2.3 USB Client Only Schematic Example
If the USB_1 port is used only as client interface (e.g. if only used for the recovery mode), the
schematic diagram can be simplified.
Figure 20: USB 2.0 client block diagram
USB_1_EN, USB_1_OC# and USB_1_ID pins are not used in this configuration. The USB_1_EN pin
can be left unconnected. The USB_1_OC# should be pulled up to 1.8V or disabled in the software.
The USB_1_ID pin needs to be pulled up to 1.8V or the OTG port needs to be configured to client
only mode in the software.
The USB_1_VBUS pin can be connected directly to the USB bus power supply of the USB Micro-B
connector. This signal is needed to indicate to the system that a host is connected at the other end
of the USB cable.

CURRENT MODE PIN CONFIGURATION
Advertise VBUS current. This 3-level input is used to control current
advertisement in DFP mode or DRP mode connected as source.
L - Default Current (0.5A for USB 2.0 or 0.9A for USB 3.0).
Pull-down to GND or leave unconnected.
M - Medium (1.5A) current. Pull-up to VDD with 500-k
Ω resistor.
H - High (3.0A) current. Pull-up to VDD with 10-k
Ω resistor.
PORT PIN CONFIGURATION
The stateof this pin is sampled when VDD is active.
H - DFP (Pull-up to VDD if DFP mode is desired)
NC - DRP (Leave unconnected if DRP mode is desired)
L - UFP (Pull-down or tie to GND if UFP mode is desired)
