On-Chip RAM Area Divisions in Boot Mode: In boot mode, the RAM area is divided into an
area used by the boot program and an area to which the programming control program is
transferred via the SCI, as shown in figure 22.11. The boot program area cannot be used until the
execution state in boot mode switches to the programming control program transferred from the
host.

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 also that the boot program
remains in this area of the on-chip RAM even after control branches to the programming
control program.
