JTAG-Booster for AMD ÉlanSC400/ÉlanSC410
2.12. Toggle CPU pins
Usage:
JTAGEL4 /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.
The signal on the defined pin has an duty cycle of 1/2: The level is 67% high and
33% low.
Please Note: Not every pin of the AMD ÉlanSC400/ÉlanSC410 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 1.8 “Initialization file JTAGEL4.INI” can be used. If
you type /PIN= without any pin declaration a list of the CPU pins is displayed.
5
/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:
JTAGEL4 /BLINK /PIN=FLAG3 /DELAY=0
This example toggles the FLAG3 pin very fast which can be followed by the use
of an oscilloscope.
