3. When executing this sample program in the on-chip ROM area or external space,
area, on-chip RAM addresses H'FF7E and H'FF7F are used. Therefore, when executing
this sample program, addresses H'FF7E and H'FF7F should not be used. In addition,
the on-chip RAM should not be disabled.

transferred. #RAMSTR in the program is the starting destination address in RAM to
which the program is transferred. #RAMSTR must be set to an even number.
#RAMSTR should be set to #START.
