Computer Operating Properly (COP)
19.1 Introduction
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 clearing the COP counter periodically. The COP module can be disabled through the COPD bit in the
configuration register 1 (CONFIG1).
19.2 Functional Description
Figure 19-1
The COP counter is a free-running 6-bit counter preceded by the 12-bit SIM counter. If not cleared by
software, the COP counter overflows and generates an asynchronous reset after 262,128 or 8176 ICLK
cycles, depending on the state of the COP rate select bit, COPRS, in the CONFIG1 register. With a
8176 ICLK cycle overflow option, a 88-kHz ICLK gives a COP timeout period of ~93ms. Writing any value
to location $FFFF before an overflow occurs prevents a COP reset by clearing the COP counter and
stages 12 through 5 of the SIM counter.
