Re: Is the x86 clock stoppable?

I haven't had homework for a very long time.
I vaguely remember being annoyed once upon a time about an unstoppable
6502. (Maybe because it used dram instead of sram for its registers, or
was there some other reason?) At the time I was told that CMOS
processors were stoppable, and that therefore maybe I'd want a 65C02.
Since AMD's and Intel's modern x86 processors are CMOS, and surely use
only sram registers, I assume that they're stoppable. But I wanted to
be sure.
I'm simply thinking about the possibility of a "pause" button on the
front of a computer, to be used instead of the power or reset button as
the emergency button of last resort to stop the operation of malicious
software, so that potentially valuable forensic evidence wouldn't be
wiped from the processor or from main memory.
That same idea was also the reason for my other posting in this
newsgroup at the same time (with subject "PC reset button resets
memory?").
