    (cont.)
    Each of the two PLDs has unique characteristics suited for its applications They are
    described in the following sections.
    9.2.1 Decode PLD (DPLD)
    The DPLD, shown in Figure 11, is used for decoding the address for internal and external
    components. The DPLD can generate the following decode signals:
    8 sector selects for the main Flash memory (three product terms each)
    4 sector selects for the Flash Boot memory
    (three product terms each)
    1 internal SRAM select signal (three product terms)
    1 internal CSIOP (PSD configuration register) select signal
    1 JTAG select signal (enables JTAG-ISP on Port E)
    2 internal peripheral select signals (peripheral I/O mode).
    9.2.2 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 8 external chip selects, routed to
    Port C or F. Although external chip selects can be produced by any Output Micro
    Cell,
    these eight external chip selects on Port C or F do not consume any Output Micro
    Cells.
    As shown in Figure 10, the CPLD has the following blocks:
    24 Input Micro
    Cells (IMCs)
    16 Output Micro
    Cells (OMCs)
    Product Term Allocator
    AND array capable of generating up to 196 product terms
    Four I/O ports.
    Each of the blocks are described in the subsections that follow.
    The Input and Output Micro
    Cells are connected to the PSD835G2 internal data bus and
    can be directly accessed by the microcontroller. This enables the MCU software to load
    data into the Output Micro
    Cells or read data from both the Input and Output
    Micro
    Cells. This feature allows efficient implementation of system logic and eliminates
    the need to connect the data bus to the AND logic array as required in most standard PLD
    macrocell architectures.
