[DSP-10] Processor stuck....???

[dsp-10@mailman.qth.net]

Hi All....maybe sombody has the same problem... (maybe it isnt a actual 
problem?)

EZ Kit in the Box, well shielded...but as soon as I put my fingers at the 
processors-top (insulated..not touching any pin !) the time-ticks go off  and 
after I take my fingers away it takes some time and normal oparation is 
resumed. Sometimes it screws up the whole program and I have to reset and 
reload both programs.

Friend Walter found out that this has to do with PIN 20 on P3:2, which leads 
to PIN 125 (the last PIN on the "Zero" corner) on the ADSP 2181 and it is an 
input Signal called  I A L .  So far I can see, this signal is not used in 
our application. If this PIN gets grounded by a 100 K resistor, everything is 
fine.

Could this cause problems and who got the same experience ???
