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 user program is transferred via the SCI, as
shown in figure 18.8. The boot program area can be used when a transition is made to the
execution state for the user program transferred to RAM.
Notes on using the boot mode
(1) When this LSI comes out of reset in boot mode, it measures the low period the input at the
(2) If any data has been written to the flash memory (if all data is not H'FF), all flash memory
(3) Interrupts cannot be used during programming or erasing of flash memory.

blocks are erased when this mode is executed. Therefore, boot mode should be used for initial
on-board programming, or for forced recovery if the program to be activated in user program
mode is accidentally erased and user program mode cannot be executed, for example.

this RAM area even after control branches to the user program.
