Some parameters are defined as a string of ASCII characters. For the string “Copyright,” the character ‘C’ is the first byte, ‘o’ is the 2nd byte, etc. When such fields are transferred, the order of transmission is:

1st character (‘C’) is on bits DD15 through DD8 of the first word

2nd character (‘o’) is on bits DD7 through DD0 of the first word

3rd character (‘p’) is on bits DD15 through DD8 of the second word

4th character (‘y’) is on bits DD7 through DD0 of the second word, etc.
