Description:
(a) After receiving the end signal for auto bit rate matching, the host machine sends H'55 to
signal the start of write control program transfer.
(b) On receipt of the H'55 signal, the boot program sends H'AA.
(c) The host machine then sends the number of bytes in the write control program as the high
digit byte followed by the low digit byte.
(d) The boot program sends back verify data for the received number of bytes (specified by the
host machine) for each digit byte (echo back).
(e) The host machine sends the write control program as binary data in 1-byte units.
(f) The boot program transfers the received write control program to internal RAM, and sends
back the verify data for each byte received (echo back).
(g) When the write control program has been received, the whole flash memory area is erased.
(h) After the whole flash memory area has been erased, the boot program sends H'AA.
(i) If the boot program cannot clear flash memory, it sends H'FF as an erase error signal.
(j) When it receives the erase error signal (H'FF), the host machine displays error message Erase
error.
(k) The boot program branches to the write control program that has been transferred to internal
RAM.
Note: The on-board programming software is transferred after the *. SUB file (S-type format)
has been converted to binary data.
