19.6.1
When boot mode is used, the flash memory programming control program must be prepared in the
host beforehand. The SCI channel to be used is set to asynchronous mode.
When a reset-start is executed after the H8S/2626 or H8S/2623 pins have been set to boot mode,
the boot program built into the LSI is started and the programming control program prepared in
the host is serially transmitted to the LSI via the SCI. In the H8S/2626 and H8S/2623, the
programming control program received via the SCI is written into the programming control
program area in on-chip RAM. After the transfer is completed, control branches to the start
address of the programming control program area and the programming control program execution
state is entered (flash memory programming is performed).
The transferred programming control program must therefore include coding that follows the
programming algorithm given later.
The system configuration in boot mode is shown in figure 19.6, and the boot mode execution
procedure in figure 19.7.
