Section 18 ROM (H8/3048F-ONE: Single Power Supply, H8/3048B Mask ROM Version)
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 18.9. 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
In boot mode in the H8/3048F-ONE, the contents of the 8-byte ID code area shown below are
checked to determine whether the program is a programming control program compatible with the
H8/3048F-ONE.
If an original programming control program is used in boot mode, the 8-byte ID code shown
above should be added at the beginning of the program.

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.
