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 3 external chip selects,
routed to Port D.
Although external chip selects can be produced by
any Output Macrocell, these three external chip
selects on Port D do not consume any Output
macrocells.
As shown in
Figure 15., page 35
, the CPLD has
the following blocks:
24 Input macrocells (IMCs)
16 Output macrocells (OMCs)
Macrocell Allocator
Product Term Allocator

AND array capable of generating up to 137

Four I/O ports.
Each of the blocks are described in the subsec-
tions 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 microcontrol-
ler. 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 logic array as required in
most standard PLD macrocell architectures.
