I do not think Cypress is in the CPLD business anymore.
But consider filing a CASE, maybe you can get some help.
To create a technical or issue case at Cypress -
“Create a Case”
You have to be registered on Cypress web site first.
Thank you Dana. I have filed a case. The ISR software that appeared to be useful for this, was not working for me, but now it is, so I may be all set. I appreciate your response.
