它可用于保存可以在执行Branch指令期间递减的循环计数。

设计的基本思路是,将时序状态编码存储,然后循环计数输出。
The basic idea is to save the code of timing state and to be of cyclic counting output.
And obviously, that ought to involve the variable in some way, or it's not going to make a lot of sense, so this includes the variable, since that's the thing that's changing.
很明显,这跟计数器的变量有某种关系,否则的话就没多大意义了,因此这跟计数器有关,因为它正是每次循环改变的东西。
