Maestro Control of External Device (Action: Transition in Progress)
In this application, Maestro can send a Transition in Progress signal to an
external device. See
Figure 60 .
Note Prior to v1.5.2, the GPO was asserted when a source began to transition. In
v1.5.2 and later the GPO is asserted as soon as the transition is triggered
whether the source begins to transition immediately or is delayed.
