      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.
