19.17.1 Boot Mode
When boot mode is used, the flash memory programming control program must be prepared in the host beforehand. The
channel 1 SCI to be used is set to asynchronous mode.
When a reset-start is executed after the H8S/2398 F-ZTAT chip’s pins have been set to boot mode, the boot program built
into the chip is started and the programming control program prepared in the host is serially transmitted to the chip via the
SCI. In the chip, 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 19-43, and the boot program mode execution procedure in
figure 19-44.
