Action Symbol
Found in the upper left-hand corner of the screen, the action symbol
rotates to indicate that the programmer is performing an operation.
Address
A coded instruction designating the location of data or program
segments in storage.
Address Offset
A value subtracted from addresses during input translation and then
added to addresses during output translation.
Algorithm
The software file containing information to program a specific device,
usually contained on a floppy disk.
Approval
Indication that a device manufacturer has tested an algorithm to support
a specific device on a programmer. The level of an approval varies by
device manufacturer, but an approval usually indicates both yield and
waveform analysis.
Baud Rate
A measure of data flow. The number of signal elements per second based
on the duration of the shortest element. When each element carries one
bit, the Baud rate is numerically equal to bits per second.
Blank Check
A device check that checks a device for programmed bits. If no
programmed bits are found, the device is considered blank.
Block Size
The hexadecimal number of bytes to be transferred in a data transfer. The
beginning of the block is defined by a begin address, and the end of the
block is the sum of the block size and the begin address minus one.
Byte Swap
See Odd/Even Byte Swap.
Communications
Parameters
The various settings that determine the I/O characteristics of your
equipment. The parameters include baud rate, stop bits, data bits, and
handshaking.

Compare Electronic ID
A command that compares the electronic signature of the socketed device
against the electronic signature specified in the currently selected
algorithm.
Compensated Vector Test
A device test that enables load compensation on PLD output pins under
test during vector testing. This may eliminate structured test error when
testing PLDs sensitive to output loading, where many of the devices
register transitions simultaneously.
Computer Remote Control
A command set that may be used to operate a programmer remotely.
These commands are usually the basis for external programmer drivers,
which may operate a programmer from a PC or other host. See also
Remote Mode.
Continuity Check
A device check that tests for open device pins before performing a device
operation.
CRC
An acronym for Computer Remote Control. See Remote Mode and
Computer Remote Control.
Cross Programming
A programming operation that allows a single generic programmable
logic device (PLD) to be configured as any one of many PLD
architectures. Consequently, the generic device can take on the function
of many subset devices. As an example, a 16V8 generic PLD can be
configured as a 16R4, 16R8, 16L8, etc.
Data Bits
A communication parameter that specifies the number of bits per byte.
Data Word Width
The word width of the data to be used during a device operation. For 8-
bit (or above) devices, the maximum is 64, and the minimum word width
is equal to the device width. For 4-bit devices, the word width can be 4, 8,
16, or 32. This value should match the word width of the data bus in the
target system for the device being programmed.
Destination
The place where you are sending something. The “something” you are
sending is almost always data. The destination can be RAM, a disk file, or
one of the programmer’s serial ports.
Device Begin Address
The first hexadecimal address of device data to use for a device operation.
If programming, it represents the first address to program. If verifying, it
represents the first address to verify.
Device Block Size
The size of device data to be used in device operations.
Device Support Packages
The method of device support for AutoSite. The device algorithms have
been organized according to package type and pin count.
Device Operation
Usually a term that refers to loading, programming, or verifying.
However, it can also refer to other available commands, such as device
checks and electronic erasing.
Device Word Width
The number of bits in the data word of the device.

DIP
A type of device package. An acronym for Dual In-line Package.
Download Data
A file operation that moves a data file from a host computer to the
programmer’s RAM or disk.
Download Echoing
Displays the data being downloaded.
Download Host Command
A command that is sent from the programmer to the host during a
download. The command tells the host to begin sending data to the
programmer.
E-MICRO
An acronym for Programmable Microcontroller. A type of device
technology.
EPROM
An acronym for Erasable Programmable Read-Only Memory. (Usually
refers to UV erasable memories.)
EEPROM
An acronym for Electronically Erasable Programmable Read-Only
Memory. The device can be either completely or partially erased
electrically in circuit or on the programmer.
Electronic ID
The combination of bytes that identify the device number and
manufacturer of a programmable device.
Enhanced Security Fuse
Capability
Found on EMICROs, the Enhanced Security Fuse Capability allows
security fuse data to be stored in a data file. For more information, or to
see if a device supports this capability, see the device manufacturer’s data
book.
ESD
An acronym for Electrostatic Discharge.
False Positive
In programming, a misprogrammed fuse that retains minimal
operational characteristics so that it passes the fuse test. These may be
inadequately programmed, or over-programmed so that they will fail
later in circuit.
File Transfer Operations
An operation involving the transfer of data between the programmer and
a host. Upload and download are file transfer operations.
Filename
The name of the disk file to use during file operations. The filename must
follow standard DOS conventions: up to eight alphanumeric characters,
followed by an optional three-character file extension, with the two fields
separated by a period. Examples of valid filenames would be
27256.dat
and
filename.c
.
Fuse Verification
A type of post-programming device check that checks the fuse pattern
programmed into a logic device with the pattern in user memory.
Fusemap
The fuse-level description portion of a programmable integrated circuit.
Fusemaps are typically files in JEDEC Standard #3A and are downloaded
to PLD programmers for device implementation.
