The result of the sum calculation ("byte + byte + byte + ・ ・ ・ ") is responded by a half-word quanti-
The checksum byte for a series of bytes of data is calculated by adding the bytes together with ignor-
Example) Assume the Show Flash Memory Sum command provides the upper and lower bytes of the
Add the bytes together
0xE5 + 0xF6 = 0x1DB
Calculate the two’s complement by using lower 8 bits, and that is the checksum byte. Then send 0x25

0xA1
0xB2
0xC3
0xD4
For the interest of simplicity, assume the depth of the flash
memory is four location. Then the sum of the four bytes is
calculated as :
Hence, 0x02 is first sent to the controller, followed by 0xEA.
0xA1 + 0xB2 + 0xC3 + 0xD4 = 0x02EA
