    al circular buffer. The Enhanced Mini-ACE/-ACE RT allows for a
    mix of single buffered, double buffered, and individually circular
    buffered subaddresses, along with the use of the global double
    buffer for any arbitrary group of receive(/broadcast) or broadcast
    subaddresses.
    In the global circular buffer mode, the data for multiple receive
    subaddresses is stored in the same circular buffer data structure.
    The size of the global circular buffer may be programmed for 128,
    256, 512, 1024, 2048, 4096, or 8192 words, by means of bits 11,
    10, and 9 of Configuration Register #6. As shown in TABLE 40,
    individual subaddresses may be mapped to the global circular
    buffer by means of their respective subaddress control words.
    The pointer to the Global Circular Buffer will be stored in location
    0101 (for Area A), or location 0105 (for Area B).
    The global circular buffer option provides a highly efficient
    method for storing received message data. It allows for frequent-
    ly used subaddresses to be mapped to individual data blocks,
    while also providing a method for asynchronously received mes-
    sages to infrequently used subaddresses to be logged to a com-
    mon area. Alternatively, the global circular buffer provides an
    efficient means for storing the received data words for all subad-
    dresses. Under this method, all received data words are stored
    chronologically, regardless of subaddress.
