Automatic Alignment of SCI Bit Rate
When started in boot mode, the H8/3437SF measures the low period in asynchronous SCI data
(H'00) transmitted from the host. The data format is eight data bits, one stop bit, and no parity bit.
From the measured low period (9 bits), the H8/3437SF computes the host’s bit rate. After aligning
its own bit rate, the H8/3437SF sends the host one byte of H'00 data to indicate that bit-rate
alignment is completed. The host should check that this alignment-completed indication is
received normally and send one H'55 byte back to the H8/3437SF. If the alignment-completed
indication is not received normally, the H8/3437F should be reset, then restarted in boot mode to
measure the low period again. There may be some alignment error between the host’s and
H8/3437SF’s bit rates, depending on the host’s transmission bit rate and the H8/3437SF’s system
clock frequency (f
4800, or 9600 bps.
Table 21.7 lists typical host transfer bit rates and indicates the system clock frequency ranges over
which the H8/3437SF can align its bit rate automatically. Boot mode should be used within these
frequency ranges.

RAM Area Allocation in Boot Mode: In boot mode, the 128 bytes from H'FF00 to H'FF7F are
reserved for use by the boot program, as shown in figure 21.9. The user program is transferred into
the area from H'F780 to H'FDFF (1664 bytes). The boot program area can be used after the
transition to execution of the user program transferred into RAM. If a stack area is needed, set it
within the user program.
