(2) On-Chip RAM Area Divisions in Boot Mode
In boot mode, the 2048-byte area from H'FFEFB0 to H'FFF7AF is reserved for use by the
boot program, as shown in figure 7.10. The area to which the programming control program
is transferred is H'FFF7B0 to H'FFFF2F (1920 bytes). The boot program area can be used
when the programming control program transferred into RAM enters the execution state. A
stack area should be set up as required.
Note: *
The boot program area cannot be used until a transition is made to the execution
state for the programming control program transferred to RAM. Note that the boot
program reamins stored in this area after a branch is made to the programming
control program.
