10. The data in bytes 37 to 44 sent by the device is the dummy data.

11. The data in bytes 45 to 46 sent by the device is the dummy data

12. The data in bytes 47 to 50 sent by the device is the flash memory start address.

This data consists of the values 00H, 00H, 01H and 00H and is transmitted

starting from the 47th byte.

13. The data in bytes 51 to 54 sent by the device is the flash memory end address.

This data consists of the values FFH, FFH, 08H and 00H and is transmitted

starting from the 51st byte.

14. The data in bytes 55 to 56 sent by the device is the data which indicates how

many blocks the flash memory is divided into. This data consists of the values

0AH and 00H and is transmitted starting from the 55th byte.

15. The data in bytes 57 to 92 sent by the device is the data containing

information on flash memory blocks. With consecutive blocks of a given size

starting at the flash memory start address comprising one unit, this

information gives the start address of the first block, the size of the block (in

half words) and the number of blocks in each unit of a given size.

The data in bytes 57 to 65 sent by the device gives the above information for

the 64K-byte blocks (Block 0 to Block 5). Similarly, the data in bytes 66 to 74

gives the information for the 56K-byte blocks (Block 6 and Block 7), the data

in bytes 75 to 83 gives the information for the 8-Kbyte blocks (Block 8 and

Block 9). For a description of this data, please refer to Table 4.3.5.

16. The data in the 84th byte sent by the device is checksum data. This is the

low-order 8-bit value in 2’s complement representation obtained by adding

eight bits of transmit data in the fifth to the 83rd bytes not including the sign

(ignoring overflow).

17. The received data in the 85th byte is the next operation command data.
