    hello to everybody.i have a problem with this sentence:
    If 'a' is
    0, the Access Bank will be
    selected, overriding the BSR value.

    what does "overriding " mean?

    It means that if input A is zero that whatever signal is on BSR, it will be
    ignored.
    Input A is a higher priority input than the (presumably) bank select
    register BSR input.

  4. ------------------
    This is the essence of a one-bit selector. If the enable "a" is 1,
    then the BSR value is propagated, selecting the Address Bank when
    BSR is in the "address bank select-enable state", if it is zero,
    then the BSR value is "overridden" by the "a", and the Address Bank
    is always selected.

    See "selector/demultiplexer/demux/multiplexer".
