Communication Processor Module
16.10.3 USB Controller Pin Functions and Clocking
The USB controller interfaces to the USB through a differential line driver and receiver. The
OE signal enables the line driver when the USB controller transmits on the bus.
There are six I/O port pins associated with the USB port and their functionality is described in
Table 16-31. Some transceivers may need additional control lines (speed select or
low-power control), which can be supported by the general-purpose output lines.
