Computer Operating Properly (COP)
6.1 Introduction
This section describes the computer operating properly module, a free-running counter that generates a
reset if allowed to overflow. The computer operating properly (COP) module helps software recover from
runaway code. Prevent a COP reset by periodically clearing the COP counter.
