John: This article( https://wodewangzhishime.blogspot.com/2022/03/httpswodewangzhishime_73.html ) talk about real interrupt.

Me: OK.

John: Now, we look at the picture above. R0(1) and R0(3) aren't on parallel input clock line. Nor are they on the serial input clock line. What do we call it?

Me: We call it mask interrupt.

John: In code, how do we interpret a mask interrupt?

Me: Like this.

.

if (int i != 0) 

{

R0(1) is at the stage of "Mask Interrupt".

That mean, R0(1) isn't on the serial input clock line. Nor is it on the parallel input clock line.

}

John: This article (https://wodewangzhishime.blogspot.com/2023/12/sequential-99.html) mention about how the  fields work in "RAM". Or, we can intepret it in this way.
