Table 63: Device Configuration Overlay Data structure
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 0through 254 and the byte consist-
ing 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.
