John : The architect of the above circuit is that indeed,  there is no serial input line. 

.

Me: Ok.

.

John: Here's a register called "R0" the value of which has 4 bits.  They are b1, b2, b3, b4.

.

Me: Ok.

.

John: The power source of the modulator is from RJ45.  RJ45 is at the Up Cycle.  The modulator will output.  A signal is sent to "R0" through a data bus. 

.

Note: In the architect of Microsoft,  we call that a data bus instead of a parallel input output line.

.

Me: Is "R0" parallel input or serial input ?

.

John : In fact,  you can't find a serial input line or a parallel input line in this architect. What's you can find is a line called "Input line".

.

Me: Then,  how do I know that it's a serial input or parallel input ?

.

John : If there's a delayed circuit,  it's a serial input.  If there's no delayed circuit,  it's a parallel input. 

.

If (falling edge trigger = true)

{

Serial input. 

}

else 

{

 Parallel input. 

}

.

Me: You mean,  B1 can be viewed as a port of parallel input too?

.

John : Yes,.
