John : In Microsoft, we don't use the term of Parallel input output. We use the term of Data bus.

.

Me: Same thing,  in Microsoft,  we don't use the term of (Load/Shit line and Parallel Output Line). We use the term of control bus.

.

John: Let's use the term system bus. There's a register called R0 at a specific address. You may see the 2nd picture above.

.

Me: Ok.

.

John : The controller of R0 enter 2 modulator.  

.

Me: 2 Modulator ?

.

John: Yes,  We call that Dual modulator.  

.

Me: However,  the "data" and "address" of R0 only enter 1 Modulator. 

.

John: Yes,. The "data" and "address" of R0 only enter 1 Modulator.  Note: the controller of R0 enter 2 Modulators.

.

Me: Which 2 Modulators Modulators does the controller of R0 enter?

.

John: The 2 modulators which the controller of R0 enter are the modulator of Data and the modulator of control.  Let's see.

.

1) The Controller of R0 enter the "Modulator of Data". And then, this modulator output to the register of R0. 

.

2) The Controller of R0 also enter the Modulator of "Control".  And then, this modulator output to the Rugby-type control-line of R0. 

.

Me: Ok.

.

John: Those "Rugby-type" control lines include "Interrupt status line", "Load shift line", "Left/Right Shift line",  "Output availability line" and "Falling Edge triggering line". Last but not the least,  take a look. https://chihaukam.blogspot.com/2026/04/take-look_01404677856.html?m=1 . It's a Rugby type of Modulation.
.

Me: In another words,  those Rugby-type control-lines control the status of interrupt,  the status of output,  the trigger of input,  e.g., falling edge,  the status of input,  e.g., parallel or serial,  and, the direction of shifting,  of a register,  e.g., R0, in this case.

.

John: Yes,
