Functional Description and Application Information
4.35.4.1
The COP timeout rate bits CR[2:0] and the WCOP bit in the COPCTL register are loaded on rising edge of RESET from the Flash
register FOPT. See
the global address $03_FF0E during the reset sequence.
Freescale Semiconductor
COP Configuration
If the MCU is secured and being started in special single chip mode, the COP timeout rate
is always set to the longest period (CR[2:0] = 111) after COP reset.
