4.18 TTL Programming Advanced Features

More complex features are available that provide the user with the ability to construct
lists of actions to be executed when TTL input lines change state. There is one list per
TTL input. Each list contains one or more trigger points and each trigger point has
associated with it one or more actions. A trigger can be activated by a rising or falling
edge of the TTL input.
