Long- and Short-Word Responses
The device responds to long-word commands with long-word
responses and short-word commands with short-word
responses. Responses are sent during the next message
following the command. A long-word response summary is
found in
Table 2
and a short-word response summary is found
in
Table 3
, page 14.

Legend
A[3:0] = Address bits. The slave address.
B[7:0] = 8-bit A/D value.
BF = Bus Fault
BS = Status of the Bus Switch (1 = close).
DR[3:0] = I/O direction bits (1 = Output).
G[1:0] = Group assignment (the 33793 does not use these bits).
IO[3:0] = Logic level of I/O.
L[3:0] = Level to output on I/O if configured as outputs.
LO = Logic Out level at the Logic Out pin.
NV = Allows nonvolatile address programming if set to “1”.
PA[3:0] = Bus Address to set the device to.
U = Undervoltage Flag.
V[2:0] = Version number.
