Question: 

After converting a Toshiba or Morotola based design to a Cypress Neuron my design no longer works what is the problem?

Answer: 

There are a number of possible of problems.  It is wise to begin by reading the Application Note  "Designing LonWorks Nodes Using Cypress Neuron Chips" to make sure that all the right steps were taken in the migration process.  If this does not uncover any flaws refer to the document published by Echelon called "Troubleshooting LONWORKS Devices and Twisted Pair Networks" available at http://www.echelon.com/support/documentation/docs/troubl2.pdf.  Also check the the Reset pin and the oscillator behavior.
