Note.  

Bits 7:0 of this word contain the value A5h. Bits 15:8 of this word contain the data structure checksum. 
The data structure checksum is the two’s complement of the sum of all byte in words 0 through 254 and 
the byte consisting of bits 7:0 of word 255. Each byte is added with unsigned arithmetic, and overflow is 
ignored. The sum of all bytes is zero when the checksum is correct.
