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 Chip Select (ECS1-ECS2) consists of
one product 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
