XTAG-2 Hardware Manual (1.0)
3 USB Connector
The XTAG-2 uses a Standard-A type USB connector to link to a PC.
The USB connector is connected to an SMSC USB3318 high-speed transceiver using
a ULPI interface. The I/O pins for the USB transceiver are mapped to ports on the
processor as described in the tables below.
Each pin can be configured either as a 4-bit port or an 8-bit port. The configuration
is determined by the set of port initialisers used in the software.
The reset pin on the USB transceiver is mapped to a 1-bit port on the processor as
described below:
