The Suppress/Show settings determine whether the various microprocessor
operations are shown or suppressed on the logic analyzer display. The
preceding section shows the microprocessor operations which have this
option. The settings for the various operations do not affect the data which is
stored by the logic analyzer, they only affect whether that data is displayed or
not. The same data can be examined with different settings, for different
analysis requirements.
This function gives you a better analysis display in two ways. First, unneeded
information can be filtered out of the display. Second, particular operations
can be isolated by suppressing all other operations. For example, I/O
accesses can be shown, with all other operations suppressed, allowing quick
analysis of I/O accesses.
If the X or O pattern markers are turned on, and the designated pattern is found
in a state that has been Suppressed with display filtering, the following
message will appear on the logic analyzer display: "X (or O) pattern found, but
state is suppressed."
