Figure 2.83: State Machine with Multiple Patterns and Timer Elapse

In Figure 2.83, the port detects HARD_RESET, which starts the Timer. When the timer
expires, it jumps to another state. If a trigger occurs between timer start and end, the
captured trace will have corrupt frames because of hardware queue overflow.

Figure 2.84: State Machine with Timeout Pattern to Replace Timer

To overcome this limitation, use a Timeout Pattern instead of Timer. Figure 2.84 shows
the state machine using Timeout instead of Timer.
