17.4.4
The value of Device ID register, its mask value, the
value derived from applying the mask, and the 32-bit
summation of bytes are shown in Table 17-4.
From Table 17-4, the value of “DIR” is:
TABLE 17-4:
17.4.5
The values derived in previous sections (PF, BF, DCR,
DIR) are used to calculate the checksum value. First,
perform the 32-bit summation of the PF, BF, DCR and
DIR as derived in previous sections and store it in a
variable, called temp, as shown in Example 17-1.

DIR = 0x00000083 (32-bit number.)
Register
First, temp = PF + BF + DCR + DIR, which translates to:
temp = 0x7F80000 + 0x002FC010 + 0x000005D4 + 0x00000083
Adding all four values results in temp being equal to 0x0827C667
Next, the 1’s complement of temp, called temp1, is calculated:
temp1 = 1’s complement (temp), which is now equal to 0xF7D83998
Finally, the 2’s complement of temp is the checksum:
Checksum = 2’s complement (temp), which is Checksum = temp1 + 1, resulting in 0xF7D83999
