8-83. When an Nm input or output stands at its
internal 1 state, the internal logic state of each input
and each output affected by Nm is the complement of
what it would otherwise be. When an Nm input or
output stands at its internal 0 state, all inputs and
outputs affected by Nm stand at their normally
defined internal logic states.
8-84. Z (INTERCONNECTION) DEPENDENCY.
The symbol denoting interconnection dependency is
the letter
z.
8-85. Interconnecting dependency is used to indi-
cate the existence of internal logic connections
between inputs, outputs, internal inputs, and/or
internal outputs.
8-86. The internal logic state of an input or output
affected by a Zm input or output will be same as the
internal logic state of the Zm input or output, unless
modified by additional dependency notation. See
Figure 8-12 .

8-87. X (TRANSMISSION) DEPENDENCY. The
symbol X denotes transmission dependency.
8-88. When an Xm input or an Xm output stands at
its internal1 state, all input-output lines affected by
this Xm input or Xm output are bidirectionally con-
nected together and stand at the same internal logic
state or analog signal level.
8-89. When a Xm input or Xm output stands at its
internal 0 state, the connection associated with this
set of dependency notation is broken.
8-90. If a stands at its 1 state, there is a bidirectional
connection between b and c. If a stands at its 0 state
there is a bidirectional connection between c and
d:
