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 a 12-bit prescaler counter. If not cleared by
software, the COP counter overflows and generates an asynchronous reset after 2
ICLK cycles, depending on the state of the COP rate select bit, COPRS, in the CONFIG1 register. With
a 2
value to location $FFFF before an overflow occurs prevents a COP reset by clearing the COP counter
and stages 12 through 5 of the prescaler.
