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 16.10. 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.
