Glossary
DWORD. Double Word. A data element that is two words (that is, four bytes or 32 bits) in size.
Dynamic Insertion and Removal. The ability to attach and remove devices while the host is in operation.
E2PROM. See Electrically Erasable Programmable Read Only Memory.
EAS. External Architecture Specification
EAV. End of Active Video
EDGE. Enhanced Data GSM Environment. A faster version of the GSM standard. It is faster because it can carry
messages using broadband networks that employ more bandwidth than standard GSM networks.
EEPROM. See Electrically Erasable Programmable Read Only Memory.
Electrically Erasable Programmable Read Only Memory (EEPROM). Non-volatile re-writable memory
storage technology.
End User. The user of a host.
Endpoint. See Device Endpoint.
Endpoint Address. The combination of an endpoint number and an endpoint direction on a USB device. Each
endpoint address supports data transfer in one direction.
Endpoint Direction. The direction of data transfer on the USB. The direction can be either IN or OUT. IN refers to
transfers to the host; OUT refers to transfers from the host.
Endpoint Number. A four-bit value between 0H and FH, inclusive, associated with an endpoint on a USB device.
Envelope Detector. An electronic circuit inside a USB device that monitors the USB data lines and detects certain
voltage related signal characteristics.
EOF. End-of-(micro) Frame
EOL. End-of-Line. A special character or sequence of characters that marks the end of a line, just before the new
line character.
EOP. End-of-Packet
EOTD. Enhanced Observed Time Difference
ETM. Embedded Trace Macrocell. The ARM* real-time trace capability
External Port. See Port.
Eye pattern. A representation of USB signaling that provides minimum and maximum voltage levels as well as
signal jitter.
FAR. Fault Address Register. Part of the ARM* architecture.
False EOP. A spurious, usually noise-induced event that is interpreted by a packet receiver as an EOP.
FDD. The Mobile Station transmits on one frequency; the Base Station transmits on another frequency
FDM. Frequency Division Multiplexing. Each Mobile station transmits on a different frequency (within a cell).
