JTAG-Booster for AMD ÉlanSC520

2.11. Polling CPU pins while the CPU is running

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

This command is similar to the function /PIN?. But with this function any pin can

be observed, independent of the pin direction. Furthermore the CPU remains in

normal operation.

Options:

/PIN=pin_name

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

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.

Example: JTAGEL5 /SAMPLE /PIN=PITOUT2

This example samples the state of the port pin PITOUT2 (=signal for the speaker)

while the AMD ÉlanSC520 is running.
