  Description: The pascal add-on does not work with the z16f (that is
               configuration z16f2800100zcog/pashello).  This appears to be
               another ZDS-II error:  when executing the instruction
               SYSIO 0, WRITESTR a large case statement is executed.  This
               involves a call into the ZiLOG runtime library to __uwcase().
               __uwcase is passed a pointer to a structure containing jump
               information.  The cause of the failure appears to be that
               the referenced switch data is bad.
               This is submited as ZiLOG support incident 81459.

               Summary of ZiLOG analysis: "This is a ZNEO run time library problem.
               One workaround is to replace the line 58 in uwcase.asm

               From:
                      ADD       R9,#4             ; Skip handler
               To:
                      ADD       R9,#2             ; Skip handler

               And add uwcase.asm to the project.

               If the customer does not want to modify uwcase.asm then the other
               workaround is to add a dummy case and make it same as default:

               case 0x8000:
               default:

               This will make sure that uwcase is not called but ulcase is called."
  Status:      Open.  Due to licensing issues, I cannot include the modified
               uwcase in the NuttX code base.

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

  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.
