Freescale Semiconductor, Inc.
Computer Operating Properly (COP) Module
14.8.2 Stop Mode
Stop mode turns off the CGMXCLK input to the COP and clears the COP
prescaler. Service the COP immediately before entering or after exiting
stop mode to ensure a full COP timeout period after entering or exiting
stop mode.
The STOP bit in the configuration register (CONFIG) enables the STOP
instruction. To prevent inadvertently turning off the COP with a STOP
instruction, disable the STOP instruction by clearing the STOP bit.
14.9 COP Module During Break Interrupts
The COP is disabled during a break interrupt when VHI is present on the
RST pin.
