Section 18 Flash Memory [H8/3024F-ZTAT Version]
18.5.1
When boot mode is used, a flash memory programming control program must be prepared
beforehand in the host, and SCI channel 1, which is to be used, must be set to asynchronous mode.
When a reset-start is executed after setting the H8/3024F-ZTAT version’ pins to boot mode, the
boot program already incorporated in the MCU is activated, and the programming control program
prepared beforehand in the host is transmitted sequentially to the H8/3024F-ZTAT version, using
the SCI. In the H8/3024F-ZTAT version, 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 (H'FFF520) of the programming control program
area and the programming control program execution state is entered (flash memory
programming/erasing can be performed).
Figure 18.6 shows a system configuration diagram when using boot mode, and figure 18.7 shows
the boot program mode execution procedure.
