2.3.5
The ADS provides a USB On-The-Go (OTG) Full Speed interface that uses a Phillips ISP1301BS USB
transceiver connected to J10, a mini AB USB connector. The interface can function as either a USB host
or USB device. The interface provides power to the USB bus in host mode. This power may be supplied
by the Phillips part or from the external 5 volt power source through a MIC2536 power switch. For details
on the operation of this USB interface, refer to the i.MX27 data sheet. Figure 2-4 shows this USB interface
connection.
