This program (CACHE1.C or CACHE4.C) is meant to allow you to 
switch off the program cache, if necessary.

Usually the cache is initialised by the program that is loaded
at RESET from flash memory.  (This program is either the HUNT
ENGINEERING bootloader program, or if you programmed the flash,
the flash romloader program (ie "rom1v1.out" or "rom4v1.out").)
These programs set the cache to off.

In case that you programmed your application into flash memory,
and your program enables the cache. If you now try to re-program
the flash memory, you may find it difficult to load the flash
programmer ("flaspro1.out" or "flaspro4.out") onto the processor.
These programs are meant for that case.

Use CACHE1.OUT to switch the cache off on a HERON1 module. The
program only uses external memory. Make sure that the external
memory interface is correctly initialised.

Use CACHE4.OUT to switch the cache off on a HERON4 module. The
program only uses external memory. Make sure that the external
memory interface is correctly initialised.
