External Chip Select  
The CPLD also provides two External Chip Select  
(ECS1-ECS2) outputs on Port D pins that can be  
used to select external devices. Each External

term that can be configured active High or Low.  
The output enable of the pin is controlled by either  
the output enable product term or the Direction  
Register. (See Figure 58.)
