John: Let me explain the above picture. When R0(0) output, it can be a parallel output or serial output.

if it is a parallel output, R0(0) output to the parallel output line.

if it is a serial output, R0(0) output to R0(1).

.

John: Do you see a circuit of tri state buffer?

Me: Yes,.

John: The function of the circuit of tri state buffer is.

.

If (parallel output control line = 1)

{

R0(0) parallel ouput. <--- the circuit of the tri state buffer is 1.

}

else if ( parallel output control line = 0 )

{

R0(0) serial ouput. <--- the circuit of the tri state buffer is 0.

}
