WARNING: In Advanced Mode, Short State Jump Intervals Can Cause Hardware Queue
Overflow and Corrupt Frames.
When using Advanced Mode, if too many state jumps occur in a short time, the hardware
queue can overflow, which may corrupt frames. For example, an infinite loop can cause
many state jumps in a short time. Hardware overflow can occur if interval between state
jumps is less than 60 DWORDs.
In Advanced Mode, infinite loops are usually used to check if an event occurs before a
timeout. In this case, you can use the Timeout dialog to avoid hardware queue overflow.
