a valid ASCII number, then terminate the algorithm and use the authorization
code computed in step 4 above.
EXAMPLE
Use the five steps above to interpret a FLASHKEY.TXT file that has the first four
characters “1234”.
1) The authorization code = 0
2) First character is “1”. Set the authorization code equal to 1.
3) Second character is “2”. Multiply the authorization code by 10 and then add 2.
The authorization code = 10 * 1 + 2, or 12.
4) Third character is “3”. Multiply the authorization code by 10 and then add 3. The
authorization code = 10 * 12 + 3, or 123.
5) Fourth character is “4”. Multiply the authorization code by 10and then add 4.
The authorization code = 10 * 124 + 4, or 1234.
The user would be required to enter an authorization code of 1234 before a firmware
update would be allowed.
EXAMPLE
Another example would be a FLASHKEY.TXT file that has the first four characters
“54ab”.
1) The authorization code = 0
2) First character is “5”. Set the authorization code equal to 5.
3) Second character is “4”. Multiply the authorization code by 10 and then add 4.
The authorization code = 10 * 5 + 4, or 54.
4) Third character is “a”. The character is not a valid ASCII number and thus, the
scan is terminated with an authorization code of 54 as computed in step 3.
EXAMPLE
A final example would be a FLASHKEY.TXT file that has the first four characters
“A111”.
1) The authorization code = 0
2) First character is “A”. The character is not a valid ASCII number and the scan is
terminated with an authorization code of 0.
