6 Keep Current
From this point forward, the operation is the same as using a regular
algorithm. Refer to your programmer User Manual for instructions.
Not on Standard List
If the algorithm is not listed in the standard device list, in terminal mode
use
Select Device / (1) Keep Current
. The algorithm can be selected from
the Select Device menu, but it cannot be added to the device list.
From this point forward, the operation is the same as using a regular
algorithm. Refer to your programmer User Manual for instructions.
Sample Keep Current Scenario
The following example illustrates a typical Keep Current scenario:
1. In May, you update your system software to version
X
.4. At the same
time, you enroll in the Keep Current Subscription Service.
2. In June, Cruft Technologies announces a new device, the Cruft 1263.
3. A week later, Data I/O announces support for the Cruft 1263 and
places a Keep Current algorithm for the Cruft 1263 on the Keep
Current BBS and the Data I/O Web page.
4. The next day you connect to the Keep Current Library via the BBS or
the Web page and download the new algorithm for the Cruft 1263.
5. In August, Data I/O releases version
X
.5 system software, complete
with the new algorithm for the Cruft 1263.
6. You update your programmer to version
X
.5 system software. The
algorithm for the Cruft 1263 is part of the system software.

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.
Glossary
Glossary-2 AutoSite User Manual
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.
