     7JTAG and Caching
     8================
     9If data or code caching is enabled on certain revisions of the PPC603e,
     10then the JTAG emulator interface become disfunctional.  You can not
     11debug using the emulator on these chip revisions.  On certain revisions,
     12it is so bad that when code caching is enabled, you can not even
     13download code reliably to the board.

     15Caching and Peripherals
     16=======================
     17When caching is enabled, care must be exercised to insure that all
     18peripheral addresses are still uncached.
