(31) The 21st to 24th bytes, transmitted from the target board to the controller, indicate the start address
(32) The 25th to 28th bytes, transmitted from the target board to the controller, indicate the start address
(33) The 29th to 32nd bytes, transmitted from the target board to the controller, are dummy data (FFH,
(34) The 33rd to 36th bytes, transmitted from the target board to the controller, indicate the end address
(35) The 37th to 40th bytes, transmitted from the target board to the controller, are 00H, 70H, FDH and
(36) The 45th and 46th bytes, transmitted from the target board to the controller, indicate the presence
(37) The 47th to 50th bytes, transmitted from the target board to the controller, indicate the start address
(38) The 51st to 54th bytes, transmitted from the target board to the controller, indicate the end address
(39) The 55th to 56th bytes, transmitted from the target board to the controller, indicate the number of
(40) The 57th to 92nd bytes, transmitted from the target board to the controller, contain information
(41) The 66th byte, transmitted from the target board to the controller, is a checksum value for the 5th
(42) The 67th byte is the next command code.

or absence of the security and protect bits and whether the flash memory is divided into blocks. Bit
0 indicates the presence or absence of the security bit; it is 0 if the security bit is available. Bit 1
indicates the presence or absence of the protect bits; it is 0 if the protect bits are available. If bit 2
is 0, it indicates that the flash memory is divided into blocks. The remaining bits are undefined.
The 45th and 46th bytes are 01H, 00H.

about the flash blocks.
Flash blocks of the same size are treated as a group. Information about the flash blocks indicate the
start address of a group, the size of the blocks in that group (in halfwords) and the number of the
blocks in that group.
The 57th to 65th bytes are the information about the 128-kbyte blocks (Block 0 to Block 7). See
Table 3.5 for the values of bytes transmitted.
to 65th bytes. The checksum value is calculated by adding all these bytes together, dropping the
carry and taking the two’s complement of the total sum.
