Operation/Comment
No change in logic.
The data on the serial DATA IN line is loaded into
serial register. The first bit clocked into the serial register
appears at DATA OUT 80 clocks later.
The data on the parallel data lines, D0 to D4, are
loaded into the 80 bit serial shift register location
addressed by A0 to A3.
Data in the 80-bit 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.
