    External Bus Controller
    All of the external memory accesses are performed by a particular on-chip External Bus
    Controller (EBC). It can be programmed either to Single Chip Mode when no external
    memory is required, or to one of two different external memory access modes, which are
    as follows:
    16-bit Addresses, 16-bit Data, Multiplexed
    11-bit Addresses, 8-bit Data, Multiplexed
    Both addresses and data use PORT0 for input/output.
    Important timing characteristics of the external bus interface (Memory Cycle Time,
    Memory Tri-State Time, Length of ALE and Read Write Delay) have been made
    programmable to allow the user the adaption of a wide range of different types of
    memories and external peripherals.
    In addition, up to 4 independent address windows may be defined (via register pairs
    ADDRSELx / BUSCONx) which control the access to different resources with different
    bus characteristics. These address windows are arranged hierarchically where
    BUSCON4 overrides BUSCON3 and BUSCON2 overrides BUSCON1. All accesses to
    locations not covered by these 4 address windows are controlled by BUSCON0.
    Note: The programmable bus features and the window mechanism are standard
    features of the C166 architecture. Due to the C164CM’s limited external address
    space, however, they can be utilized only to a small extend.
    The C164CM will preferably be used in single-chip mode. Applications which require
    access to external resources such as peripherals or small memories, will use the 8-bit
    data bus with 11-bit address bus in most cases. In this case the upper pins of PORT0
    can be used for the serial interfaces. If a wider address or a 16-bit data bus is required
    the serial interfaces cannot be used.
