EPATtern
Command/Query The EPATtern command is used to specify the event patterns used by the
WAIT and IF commands. The pattern generator has three external input
qualifiers (WAIT2, WAIT1, and WAIT0). There are eight combinations of the
three input qualifiers that may be OR’ed together to create an event pattern
specification. Mapping of these input qualifier patterns to an event pattern
specification is shown below.
