Complex PLD (CPLD)
The CPLD can be used to implement system logic functions, such as loadable counters and
shift registers, system mailboxes, handshaking protocols, state machines, and random logic.
The CPLD can also be used to generate External Chip Select (ECS1-ECS2), routed to Port
D.
Although External Chip Select (ECS1-ECS2) can be produced by any Output Macrocell
(OMC), these External Chip Select (ECS1-ECS2) on Port D do not consume any Output
Macrocells (OMC).
