SHORT INSTRUCTION VECTOR

V: these bits are set 001 for a short instruction vector.

WN: word number of vector (2 to 87 decimal) (Table 46).

WN describes the location of the vector word in the frame.

e: error (Table 46). 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 (Table 46). This is the phase on which the vector

was found (0 = A, 1 = B,2=Cand3=D).

i: instruction type (Tables 46 and 47). These bits define

the meaning of the d bits in this packet.

x: unused bits (Table 46). The value of these bits is not

guaranteed.

d: data bits whose definition depend on the value of the

i bits in this packet according to Table 47. Note that if this

vector is received on a long address and the e bit in this

packet is not set, the decoder sends a message packet

immediately following the vector packet. All message bits

in the message packet are unused and should be ignored.
