CY14B256Q2A access methodology problem - Cypress.com Forums http://www.cypress.com/? Re: CY14B256Q2A access methodology problem http://www.cypress.com/?rID=58622 Well this is embarassing.  I've answered my own question.  Yes the part is fully static and can tolerate the clock stopping between ending a command and reading the results.  I had it in my head that there was a non-zero value in the status register at powerup.  Wrong.  I was indead reading the status register and it's value was zero.  As soon as I wrote a WREN command (write enable) and read the status register I got back a value of two.

After that everything works fine.  Thanks for the time and sorry about the noise.
