JTAG-Booster for AMD ÉlanSC520

46 JTAGEL5d.doc

2.9. Toggle CPU pins

Usage: JTAGEL5 /BLINK /PIN=pinname [optionlist]

This command allows to test the hardware by blinking with LEDs or toggling CPU

signals. Faster signals can be generated by setting the delay option to zero. This

can be a very helpful feature to watch signals on an oscilloscope.

Please Note: Not every pin of the AMD ÉlanSC520 may be specified as an output

pin.

Options:

/PIN=pin_name

CPU pin to toggle. If the option /PIN= is not specified an error message occurs.

Most pins of the list in chapter 1.6 “Initialization file JTAGEL5.INI” can be used. If

you type /PIN= without any pin declaration a list of the CPU pins is displayed.

/DELAY=dddddd

Time to wait to next change of signal. This option can be adjusted to get optimum

signals for measures with the oscilloscope.

Default: /DELAY=10000

Example: JTAGEL5 /BLINK /PIN=CS0# /DELAY=0

This example toggles the CS0# pin very fast which can be followed by the use of

an oscilloscope.

dddddd=number base is decimal
