    PLDS
    The PLDs bring programmable logic functionality
    to the PSD. After specifying the logic for the PLDs
    using the PSDabel tool in PSDsoft Express, the
    logic is programmed into the device and available
    upon Power-up.
    The PSD contains two PLDs: the Decode PLD
    (DPLD), and the Complex PLD (CPLD). The PLDs
    are briefly discussed in the next few paragraphs,
    and in more detail in the section entitled
    Decode
    PLD (DPLD), page 35
    and the section entitled
    Complex
    PLD
    (CPLD), page 36
    .
    13., page 34
    shows the configuration of the PLDs.
    The DPLD performs address decoding for Select
    signals for internal components, such as memory,
    registers, and I/O ports.
    The CPLD can be used for logic functions, such as
    loadable counters and shift registers, state ma-
    chines, and encoding and decoding logic. These
    logic functions can be constructed using the 16
    Output Macrocells (OMC), 24 Input Macrocells
    (IMC), and the AND Array. The CPLD can also be
    used to generate External Chip Select (ECS0-
    ECS2) signals.
    The AND Array is used to form product terms.
    These product terms are specified using PSDabel.
    An Input Bus consisting of 73 signals is connected
    to the PLDs. The signals are shown in Table
    14
    .
    The Turbo Bit in PSD
    The PLDs in the PSD can minimize power con-
    sumption by switching off when inputs remain un-
    changed for an extended time of about 70ns.
    Resetting the Turbo Bit to '0' (Bit 3 of PMMR0) au-
    tomatically places the PLDs into standby if no in-
    puts are changing. Turning the Turbo mode off
    increases propagation delays while reducing pow-
    er consumption. See the section entitled
    POWER
    MANAGEMENT, page 62
    on how to set the Turbo
    Bit.
    Figure
    Additionally, five bits are available in PMMR2 to
    block MCU control signals from entering the PLDs.
    This reduces power consumption and can be used
    only when these MCU control signals are not used
    in PLD logic equations.
    Each of the two PLDs has unique characteristics
    suited for its applications. They are described in
    the following sections.
