Technical Data

The clock monitor is a useful backup to the COP watchdog system.
Because the watchdog timer requires a clock to function, it cannot
indicate a system clock failure. The clock monitor would detect such a
condition and force the MCU to a reset state. Clocks are not required for
the MCU to reach a reset condition. They are, however, required to bring
the MCU through the reset sequence and back to run condition.
