    Input Macrocells (IMC)
    The Input Macrocells (IMC) can be used to latch or
    store external inputs. The outputs of the Input
    Macrocells (IMC) are routed to the PLD input bus,
    and can be read by the MCU. See the section en-
    titled
    PLDS, page 33
    .
    Enable Out
    The Enable Out register can be read by the MCU.
    It contains the output enable values for a given
    port. A 1 indicates the driver is in output mode. A
    0 indicates the driver is in tri-state and the pin is in
    input mode.
    Ports A and B – Functionality and Structure
    Ports A and B have similar functionality and struc-
    ture, as shown in Figure
    28
    . The two ports can be
    configured to perform one or more of the following
    functions:
    MCU I/O Mode
    CPLD Output – Macrocells McellAB7-
    McellAB0 can be connected to Port A or Port
    B. McellBC7-McellBC0 can be connected to
    Port B or Port C.
    CPLD Input – Via the Input Macrocells (IMC).
    Latched Address output – Provide latched
    address output as per
    Table 21., page 54
    .
    Address In – Additional high address inputs
    using the Input Macrocells (IMC).
    Open Drain/Slew Rate – pins PA3-PA0 and
    PB3-PB0 can be configured to fast slew rate,
    pins PA7-PA4 and PB7-PB4 can be
    configured to Open Drain Mode.
    Data Port – Port A to D7-D0 for 8 bit non-
    multiplexed bus
    Multiplexed Address/Data port for certain
    types of MCU bus interfaces.
    Peripheral Mode – Port A only
