John: The above picture is the process of output of RJ45. The first step is MOV Port C, value.

Me: And then?

.

1) The data input of R3 is from the data output of R2 (R2 right shift to R3)

2) The data input of R2 is from the data output of R1. (R1 right shift to R2)

.

John: Then, where is the data input of R1 from?

Me: From the clock line.

John: That mean, the data-input line of R1 is linked to the clock line.

Me: Correct. When the clock line is up cyle, R1 is being triggered. We call that point as "Output triggering point".

John: When Port A is triggered, R1 right shift to R2, R2 right shift to R3, etc.

Me: Finally, R3 output.
