Addresses 6 to 17 and
19 of
the buffer are areas exclusively used for
reading from the PC CPU. Because the A64RDC overwrites digital data in
these areas always destroying the data in the buffer. In this case, the
A64RDC detects an error, stores the error code in address
18 and flickers
the RUN LED.
