    Input Macrocells (IMC)
    The CPLD has 24 Input Macrocells (IMC), one for
    each pin on Ports A, B, and C. The architecture of
    the Input Macrocells (IMC) is shown in 
    Figure
    17., page 41
    . The Input Macrocells (IMC) are indi-
    vidually configurable, and can be used as a latch,
    register, or to pass incoming Port signals prior to
    driving them onto the PLD input bus. The outputs
    of the Input Macrocells (IMC) can be read by the
    MCU through the internal data bus.
    The enable for the latch and clock for the register
    are driven by a multiplexer whose inputs are a
    product term from the CPLD AND Array or the
    MCU Address Strobe (ALE/AS). Each product
    term output is used to latch or clock four Input
    Macrocells (IMC). Port inputs 3-0 can be con-
    trolled by one product term and 7-4 by another.
    Configurations for the Input Macrocells (IMC) are
    specified by equations written in PSDabel (see Ap-
    plication Note 
    AN1171
    ). Outputs of the Input Mac-
    rocells (IMC) can be read by the MCU via the IMC
    buffer. 
    See 
    the 
    section 
    PORTS, page 51
    .
    entitled 
    I/O
    Input Macrocells (IMC) can use Address Strobe
    (ALE/AS, PD0) to latch address bits higher than
    A15. Any latched addresses are routed to the
    PLDs as inputs.
    Input Macrocells (IMC) are particularly useful with
    handshaking communication applications where
    two processors pass data back and forth through
    a common mailbox. 
    Figure 18., page 42
     shows a
    typical configuration where the Master MCU writes
    to the Port A Data Out Register. This, in turn, can
    be read by the Slave MCU via the activation of the
    “Slave-Read” output enable product term.
    The Slave can also write to the Port A Input Mac-
    rocells (IMC) and the Master can then read the In-
    put Macrocells (IMC) directly.
    Note that the “Slave-Read” and “Slave-Wr” signals
    are product terms that are derived from the Slave
    MCU inputs Read Strobe (RD, CNTL1), Write
    Strobe (WR, CNTL0), and Slave_CS.
