JTAG-Booster for AMD ÉlanSC520
14 JTAGEL5d.doc
1.6. Initialization file JTAGEL5.INI
This file is used to set the CPU signals for input/output. In case of output signal an
additional parameter is used to set the default level to high or low. This file can be
used to adapt your own AMD ÉlanSC520 design to the JTAG-BOOSTER. The
Target-Entry is used to identify your design which is displayed with most
commands.
When the JTAGEL5 software is started it scans the current directory for an
existing initialization file named JTAGEL5.INI. If no entry is found the default values
are used. You may also specify the initialization file with the option
/INI= . If the specified file isn't found, the program aborts with an error message.
The CPU pins can also be used with the functions /BLINK (chapter 2.9), /PIN?
(chapter 2.10) and /SAMPLE (chapter 2.11) to test the signals on your design.
Example of JTAGEL5.INI:
// Description file for AMD ÉlanSC520
Target: FS FORTH-SYSTEME, EVA520
// All chip select signals are set to output and inactive.
// All signals should be defined. Undefined signals are set to their defaults.
// Pin names are defined in upper case.
// Low active signals are signed with a trailing #.
// Group A: All pins in this group must be set to the same direction
// This pins are tristateable outputs and may not be read back
