WN:
Word number of vector (2 - 87 decimal). Describes the location of the vector word in the
frame.
e:
Set if more than 2 bit errors are detected in the word, if the check character calculation fails
after error correction has been performed, or if the vector value is determined to be invalid.
p:
Phase on which the vector was found (0=a, 1=b, 2=c, 3=d)
n:
Number of message words in this frame including the first Message word that immediately
follows a long address vector. Valid values are 1 through 85 decimal.
b:
Word number of message start in the message field. Valid values are 3 through 87 decimal.
x:
Unused bits. The value of these bits is not guaranteed.
Note: For long addresses, the first Message Packet is sent from the word location immediately
following the word location of the Vector Packet. The b bits indicate the second message
word in the message field if one exists.
