Revision(s) Affected: A, B, E
In the EPI module, many new features have been added on silicon revisions A and onwards. New configuration registers have been added to enable new features. However, in some cases, new configuration bits (which were “Reserved” on the revision 0 silicon) have been added to existing registers, without breaking the compatibility with the revision 0 silicon. Users should refer to the "External Peripheral Interface (EPI)" chapter in the Concerto F28M35x Technical Reference Manual to make sure their existing EPI code (which works on the revision 0 silicon) is not changing the default value of the new configuration bits. Otherwise, the old code may not work on the new silicon.
