    MCU I/O Mode
    In the MCU I/O mode, the MCU uses the I/O Ports
    block to expand its own I/O ports. By setting up the
    CSIOP space, the ports on the PSD are mapped
    into the MCU address space. The addresses of
    the ports are listed in
    Table 7., page 18
    .
    A port pin can be put into MCU I/O mode by writing
    a 0 to the corresponding bit in the Control Regis-
    ter. The MCU I/O direction may be changed by
    writing to the corresponding bit in the Direction
    Register, or by the output enable product term.
    See
    the
    section
    entitled
    Mode, page 55
    . When the pin is configured as an
    output, the content of the Data Out Register drives
    the pin. When configured as an input, the MCU
    can read the port input through the Data In buffer.
    See
    Figure 26., page 52
    .
    Ports C and D do not have Control Registers, and
    are in MCU I/O mode by default. They can be used
    for PLD I/O if equations are written for them in PS-
    Dabel.
    PLD I/O Mode
    The PLD I/O Mode uses a port as an input to the
    CPLD’s Input Macrocells (IMC), and/or as an out-
    put from the CPLD’s Output Macrocells (OMC).
    The output can be tri-stated with a control signal.
    This output enable control signal can be defined
    by a product term from the PLD, or by resetting the
    Peripheral
    I/O
    corresponding bit in the Direction Register to ’0.’
    The corresponding bit in the Direction Register
    must not be set to '1' if the pin is defined for a PLD
    input signal in PSDabel. The PLD I/O mode is
    specified in PSDabel by declaring the port pins,
    and then writing an equation assigning the PLD I/
    O to a port.
    Address Out Mode
    For MCUs with a multiplexed address/data bus,
    Address Out Mode can be used to drive latched
    addresses on to the port pins. These port pins can,
    in turn, drive external devices. Either the output
    enable or the corresponding bits of both the Direc-
    tion Register and Control Register must be set to
    a 1 for pins to use Address Out Mode. This must
    be done by the MCU at run-time. See Table
    21
    for
    the address output pin assignments on Ports A
    and B for various MCUs.
    For non-multiplexed 8-bit bus mode, address sig-
    nals (A7-A0) are available to Port B in Address Out
    Mode.
    Note:
    Do not drive address signals with Address
    Out Mode to an external memory device if it is in-
    tended for the MCU to Boot from the external de-
    vice. The MCU must first Boot from PSD memory
    so the Direction and Control register bits can be
    set.
