USB Sample Clock Input is used to synchronize an external clock to the
internal USB peripheral controller for isochronous transfers.
USB Start of Frame is a 1-kHz frame pulse used to synchronize USB
isochronous transfers to an external device on a frame-by-frame basis.
USB External Transceiver Differential Minus is an output that drives the
external transceiver differential driver minus input.
USB External Transceiver Differential Plus is an output that drives the
external transceiver differential driver plus input.
USB External Transceiver Transmit Output Enable is an output that enables
the external transceiver. UXVOE signals the external transceiver that USB data
is being output by the Am186CC USB controller. When Low, this pin enables the
transceiver output; when High, this pin enables the receiver.
USB External Transceiver Differential Receiver is a data input received from
the external transceiver differential receiver.
