               uwcase in the NuttX code base.
  Priority:    Medium

  Description: Add support to maintain SPOV in context switching.  This
               improvement will provide protection against stack overflow
               and make a safer system solution.

  Description: Add support for prioritized interrupts.  Currently logic supports
               only nominal interrupt priority.

  Description: The file drivers/mmcsd/mmcsd_sdio.c generates an internal compiler
               error like:
 
               mmcsd\mmcsd_sdio.c
               Internal Error(0503) On line 2504 of "MMCSD\MMCSD_SDIO.C"
                   File <c3>, Args(562,46)

  Status:     Open.  Recommended workaround: remove mmcsd_sdio.c from
              drivers/mmcsd/Make.defs.  There is no SDIO support for the Z16 anyway

  ^^^^^^^^^^^^^^^^^^

  Description: There is no script for building in banked mode (more correctly, there
               is a script, but logic inside the script has not yet been implemented).
               It would be necessary to implement banked mode to able to access more
               the 48Kb of FLASH.
