Flash Memory Sum command adds all 512 Kbytes of the flash memory together and provides the total sum
as a halfword quantity. The sum is sent to the controller, with the upper eight bits first, followed by the lower
eight bits.
carries, and taking the two’s complement of the total sum. The Show Flash Memory Sum command and the
Show Product Information command perform the checksum calculation. The controller must perform the
same checksum operation in transmitting checksum bytes.
as 0xE5 and 0xF6. To calculate the checksum for a series of 0xE5 and 0xF6:
The result of the sum calculation "byte + byte + byte + ・・・" is responded by a word quantity. The Show
The checksum byte for a series of bytes of data is calculated by adding the bytes together, dropping the
Example) Assume the Show Flash Memory Sum command provides the upper and lower bytes of the sum
Add the bytes together
0xE5 + 0xF6 = 0x1DB
Take the two’s complement of the sum, and that is the checksum byte.
0 − 0xDB = 0x25

area through 0x007_FFFF area are calculated as "0xFF".
Example)
0xA1
0xB2
0xC3
0xD4
For the interest of simplicity, assume the depth of the flash
memory is four locations. Then the sum of the four bytes is
calculated as:
0xA1 + 0xB2 + 0xC3 + 0xD4 = 0x02EA
Hence, 0x02 is first sent to the controller, followed by 0xEA.
