Event Controller Function 

1. 

 

Overview of the event controller 

The event controller is used to determine how the control signals between the various functions are 
interlinked.  Customizing the way in which the control signals are used allows more advanced 
operations to be implemented by synchronizing the different functions within a single device and by 
synchronizing operation between multiple devices. 

 

 

 

The arrows in the figure show the flow of control signals. 
The main control signals include the operation start signals, operation stop signals, and clock signals.
