        9.3 Microcontroller Bus Interface
        The
        no-glue logic
        PSD4000 Microcontroller Bus Interface can be directly connected to
        most popular microcontrollers and their control signals. Key 16-bit microcontrollers with
        their bus types and control signals are shown in Table 14. The MCU interface type is
        specified using the PSDsoft.

        Unused CNTL2 pin can be configured as GPLD input. Other unused pins (PD3-0, PF3-0) can be

        configured for other I/O functions.

        ALE/AS input is optional for microcontrollers with a non-multiplexed bus.
        ***
        This configuration is for 68C812A4_EC at 5MHz, 3V only.
        9.3.1. PSD4000 Interface to a Multiplexed Bus
        Figure 16 shows an example of a system using a microcontroller with a 16-bit multiplexed
        bus and a PSD4000. The ADIO port on the PSD4000 is connected directly to the
        microcontroller address/data bus. ALE latches the address lines internally. Latched
        addresses can be brought out to Port E, F or G. The PSD4000 drives the ADIO data bus
        only when one of its internal resources is accessed and the RD input is active. Should the
        system address bus exceed sixteen bits, Ports A, B, C, or F may be used as additional
        address inputs.
        9.3.2. PSD4000 Interface to a Non-Multiplexed Bus
        Figure 17 shows an example of a system using a microcontroller with a 16-bit
        non-multiplexed bus and a PSD4000. The address bus is connected to the ADIO Port, and
        the data bus is connected to Port F and G. Port F and G are in tri-state mode when the
        PSD4000 is not accessed by the microcontroller. Should the system address bus exceed
        sixteen bits, Ports A, B or C may be used for additional address inputs.
