John: See this article. https://kamchihau.blogspot.com/2024/07/sequential-109.html . In reality, there's no serial circuit.

Me: This article mention ( https://wodewangzhishime.blogspot.com/2022/04/httpswodewangzhishime_23.html ) about the importance of a gap.

.

John: This article (https://wodewangzhishime.blogspot.com/2022/02/bach-request-poison-gas-from.html) mention about "which" picture is correct.

.

Me: OK. Now, we look at the 2nd picture. It is a circuit of "flip and flop" called R0(1).

.

if (the gate of Setting of R0(1) = 1 & the gate of resetting of R0(1) =0)

{

if (the clock line of setting of R0(1) is 1 & the clock line of resetting of R0(1) is 1) 

{

The output of the setting of R0(1) is false;

The output of the resetting of R0(1) is true;

The status of R0(1) = stable.

}

}

.

John: However, hacker may create the following phenomenon.

.

.

if (the gate of Set of R0(1) = 1 & the gate of reset of R0(1) =0)

{

if (the clock line of set of R0(1) = 0 & the clock line of reset of R0(1) =1) 

{

The output of the setting of R0(1) is true;

The output of the resettig of R0(1) is true;

The status of R0(1) = Unstable. <---- It become a gap.

}

}

.

John: Look at the 1st picture. If R0(1) is unstable, R0(1) become a gap.

.

if (R0(1) = gap)

{

everything after R01 become a "New" register.

}
