4.1 Introduction
4.2 Functional Description
MC68HC908RF2 — Rev. 4.0
MOTOROLA
The computer operating properly (COP) module contains a free-running counter
that generates a reset if allowed to overflow. The COP module helps software
recover from runaway code. Prevent a COP reset by periodically clearing the COP
counter.
