Computer Remote Control
If you exit remote mode using the Z command, the programmer's parameters
are set to what they were before you entered remote mode. If you exit using
CTRL + Z, the programmer's parameters are NOT changed.
CRC commands are simplified commands for the programmer that are
designed to be received from a controlling computer. Because the commands
are so simplified, they can be cryptic at times.
CRC Command Summary
You send CRC commands to the programmer by typing the command and then
pressing the ENTER key. When the programmer receives a CRC command, the
command is executed and a response is sent back, followed by a carriage
return. If the response is an F, an error occurred. If the response is a ?, the
programmer did not understand the command. If the response is a >, the
normal CRC prompt, the command executed properly. Some commands
respond with both a value and the prompt. For example, the programmer
might return 00284295> when you send the Calculate Sumcheck command. In
this case, the 00284295 is the sumcheck and the > indicates that the command
executed properly. The I, O, and C commands perform any data transfer prior
to sending the response.
Each command in the CRC command set is summarized in the following tables.
For a more detailed explanation of CRC commands, refer to the “UniSystem
Computer Remote Control” Application Note (983-0490) available from
Customer Support. The command tables are broken up into standard and
extended CRC commands. Standard CRC commands are commonly used
commands, such as Load, Program, and Verify. Extended CRC commands are
more specific device-related commands, such as Set Security Fuse, Fill Fuse
Map, and Set Vector Test Options.
Note: While in CRC mode, the programmer recognizes only
uppercase characters.
Except where noted, the commands use the following notation conventions:
� lower-case alphabetic characters indicate arguments that must be specified
� h represents a hexadecimal digit.
� n represents a decimal digit.
� xxx...xxxx represents a string of characters. Filenames are limited to 12
total characters: name (eight characters), a period (one character), and an
extension (three characters).
For example, nn02] indicates that you may precede the 02] command with
two decimal digits.
