Hardware implementation
Figure 14-7. Host mode initialization flow
14.5.3 Voltage regulator initialization
The USB regulator is enabled by default; therefore, no initialization is required unless the
regulator was previously disabled by the software after the last POR.

Hardware implementation
14.6.1 Connection diagram
The USB 2.0 requests the D+ and D- signals, VBUS (5 V power line), ground, and in
some cases the ID pin. This ID pin is included in the OTG specification and is used when
one device can act as a host or as a device, depending on which plug is connected into the
board connector. The mini-A plug, which indicates that this part is a host, has the ID pin
grounded, while the ID in the mini-B plug is floating, indicating that this part will act as a
device.
