Complex PLD (CPLD)
The CPLD can be used to implement system logic
functions, such as loadable counters and shift reg-
isters, system mailboxes, handshaking protocols,
state machines, and random logic. The CPLD can
also be used to generate three External Chip Se-
lect (ECS0-ECS2), routed to Port D.
Although External Chip Select (ECS0-ECS2) can
be produced by any Output Macrocell (OMC),
these three External Chip Select (ECS0-ECS2) on
Port D do not consume any Output Macrocells
(OMC).
As shown in
Figure 13., page 34
, the CPLD has
the following blocks:
24 Input Macrocells (IMC)
16 Output Macrocells (OMC)
Macrocell Allocator

■
■
Product Term Allocator
AND Array capable of generating up to 137
product terms
Four I/O Ports.
Each of the blocks are described in the sections
that follow.
The Input Macrocells (IMC) and Output Macrocells
(OMC) are connected to the PSD internal data bus
and can be directly accessed by the MCU. This
enables the MCU software to load data into the
Output Macrocells (OMC) or read data from both
the Input and Output Macrocells (IMC and OMC).
This feature allows efficient implementation of sys-
tem logic and eliminates the need to connect the
data bus to the AND Array as required in most
standard PLD macrocell architectures.
