6.6.4 Traps 中说:
A trap behaves like an interrupt, but is created and controlled with software. The trap
condition can be stored in any one of the conditional registers: A1, A2, B0, B1, or B2. If
the trap condition is valid, a branch to the trap handler routine processes the trap and
the return
这句话中所说的 陷阱状态可以存储在任何一个条件寄存器中, 我想知道, 这个过程是如何实现的,从哪里可以知道陷阱的状态? 谢谢
