8.8.2 USB electrical specifications

The USB electricals for the USB On-the-Go module conform to the standards

documented by the Universal Serial Bus Implementers Forum. For the most up-to-date

standards, visit usb.org.

NOTE

The Fast IRC do not meet the USB jitter specifications for

certification for Host mode operation.
