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.
