Using 56f8367evm with external FM25L040B [Cypress FRAM].  When writing WEN flag to status register and then reading back status register using typical example and PE, data read back is 0xff BUT on the scope the data is correct.  Same thing happens when writing a data byte to the FRAM device, write a byte, then when reading back its correct on the scope, but not in the read back variable.  Is there a bug I am not aware of?  I stepped throught the PE component and even as its read in its wrong.
