V: 001 for a Short Instruction Vector
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 or, if after error correction, the check
character calculation fails.
p: Phase on which the vector was found (0=a, 1=b, 2=c, 3=d)
d: Data bits whose definition depend on the i bits in this packet according to the following table.
Note that if this vector is received on a long address and the e bit in this packet is not set, the
decoder will send a Message Packet immediately following the Vector Packet. All message bits in
the message packet are unused and should be ignored for all modes except the Temporary address
assignment with MSN (i
