Operation/Comment
No change in logic.
The data on the DATA IN line is loaded into the
serial register. The first bit clocked into the serial
register appears at DATA OUT 80 clocks later.
Data in the serial shift register transfers into the
parallel latches that control the switch array.
Latches are transparent.
Asynchronous operation. All outputs are disabled.
Remainder of logic is unchanged.
