KL46Z SPI slave bug?

I've recently moved a PE project from a KL25Z to a KL46Z.  The board acts as an SPI slave.  I noticed issues with SPI after moving, as in not working at all.


After creating some test projects and testing on both boards I seem to have found a PE bug - the KL46Z, when put in CPHA=1, never fires the OnBlockReceived event.  The same code works fine on a KL25Z put in CPHA=1.  The interrupt fires on the KL46Z if CPHA=0.


I don't see anything in the KL46 reference manual that would explain this behavior and I didn't see any errata in the documentation section for the KL46Z that pertains.  Is this a bug, or have I missed something?
