Please always keep in mind that ICE is different from IC. ICE is the whole set of HE80000 series IC, but
each IC is a subset of ICE. Never use any hardware resource that real IC didn't have, especially RAM and
register. KBIDS and compiler cannot prevent user to use some hardware resource that didn't exist. Please
check the following table and refer the abbreviation in HE80000 user's manual.
