5.2 Overview of the Versa Ware JTAG Software
Versa Ware JTAG is a Windows®-based software tool that provides a user-friendly development platform for all Ramtron
microcontrollers featuring a JTAG interface (the VRS51L2xxx, VRS51L3xxx and future derivatives).
The Versa Ware JTAG Software is composed of two parts:
Versa Ware JTAG Programmer
o
The Versa Ware JTAG Programmer is used to perform operations such as erase, program, read, etc., on the target
device's Flash memory.
Versa Ware JTAG Debugger
o
The Versa Ware JTAG Debugger is a user interface that links the in-circuit debugger and the source code. All Ramtron
MCUs with a JTAG interface include an integrated debugger that enables in-application debugging of the device via its
JTAG interface.
The Versa Ware JTAG Debugger is compatible with the SDCC, Keil and Ride compilers.
The Versa Ware JTAG software was developed on Windows XP, but should operate properly on Windows Vista and
Windows 2000 operating systems. It should also work on a Window 98 SE operating system on a computer with a UBS
interface. Users without a USB interface, can use Ramtron's parallel port version of the JTAG interface. Please contact
Ramtron to order one.
The following window shows the in-circuit debugger in action when the source code XRAM, SFR page 0, and watch list
windows are open and the program is halted at a breakpoint.
The Versa Ware JTAG Debugger provides a comprehensive set of configuration options allowing users to tailor the
user interface, watch variables and breakpoints settings.
