JTAG-Booster for Intel 386EX
2.12. Toggle CPU pins
Usage:
JTAG386 /BLINK /PIN=pinname [optionlist]
dddddd=number base is decimal
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 Intel 386EX 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 JTAG386.INI” can be used. If
you type /PIN= without any pin declaration a list of the CPU pins is displayed.
/DELAY=dddddd 5
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:
JTAG386 /BLINK /PIN=FLAG3 /DELAY=0
This example toggles the GP26 pin very fast which can be followed by the use of
an oscilloscope.
