If the "mixed" or "true demultiplexing" slave clock modes are
selected, choose "None", "rising", "falling", or "Both" for the "Edges of
J (K,L,M) clock used for slave clock" configuration options.
Four configuration options are present when you select either the "mixed" or
"demux" slave clock mode. They allow you to define the slave clock. You can
specify rising, falling, both, or neither (none) edges of the J, K, L, and M
clocks. When several clock edges are specified, any one of the edges clocks
the trace.
Clocks J and K are the external clock inputs of the external analyzer probe.
The L and M clocks are generated by the emulator. Typically, the L clock is
the emulation clock derived by the emulator and the M clock is not used.

Choose "yes" for the "Should emulation control the external bits"
configuration option.

For each defined external label (there can be up to 8), choose the
"name", "start bit", "width", and "polarity".
You can define up to eight labels for the 16 external data channels in the
configuration. These external analyzer labels can be used in trace
commands, and the data associated with these labels can be displayed in the
trace list. One external analyzer label, "xbits", is defined by the default
configuration and is included in the default trace list.
External labels can be defined with bits in the range of 0 through 15. The
start bit may be in the range 0 through 15, but the width of the label must not
cause the label to extend past bit 15. Thus, the sum of the start bit number
plus the width must not exceed 16.
The "polarity" configuration option allows you to specify positive or negative
logic for the external bits. In other words, positive means high=1, low=0.
Negative means low=1, high=0.
Once external labels are defined, they may be used in trace commands to
qualify events (if the emulation controls the external analyzer). Also, you
can modify the trace display to include data for the various trace labels.
Note that the Timing Analyzer Interface does not use the external labels
defined in the emulator/analyzer interface. You maintain labels for the timing
analyzer within the Timing Analyzer Interface itself.
