6.3.4 Data Receiving Control￿￿￿

When the BUSY signal is at LOW, the data from the host side can be received, but when at HIGH, it cannot be received.

6.3.5 Buffering

A size of the input buffer can be selected by setting the DIP switch segment DS1-4. When a 4KB buffer is selected, the host side is immediately free because a large amount of data can be buffered.
