On-Chip RAM Area Divisions in Boot Mode: In boot mode, the 2-kbyte area from H'FFDC00
to H'FFE3FF is reserved for use by the boot program, as shown in figure 17.12. The area to which
the programming control program is transferred is H'FFE400 to H'FFFBFF. 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.
H8S/2314 F-ZTAT On-Chip RAM Area Divisions in Boot Mode: In boot mode, the 2-kbyte
area from H'FFDC00 to H'FFE3FF is reserved for boot program use, as shown in figure 17.13.
The area to which the programming control program is transferred is H'FFE400 to H'FFFBFF. The
boot program area becomes available when a transition is made to the execution state for the
programming control program transferred to RAM. A stack area should be set as required.
The 4-kbyte area from H'FFDC00 to H'FFEBFF is a reserved area used only in boot mode. It
should not be used for any purpose other than flash memory programming/erasing.
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
remains stored in this area after a branch is made to the programming control program.
