... to C necessary for targeting an embedded environment, and the common components of a successful development project. C is the language of choice for programming larger microcontrollers (MCU), ... instructions to the COPCR register. Interestingly, the COP watchdog is dependent upon the system clock; a clock monitor circuit resets the MCU if the clock stops, and thereby renders the COP watchdog ... manoeuvre. Programming the prescalar and starting the clock are tasks of the software developer. Knowing the processor clock frequency, and choosing correct prescalar values, you can achieve accurate...
