CHAPTER 8 16-BIT TIMER/EVENT COUNTER 0
When the compare register is changed during timer count operation, if the value after 16-bit timer capture/
compare register 00 (CR00) is changed is smaller than that of 16-bit timer counter 0 (TM0), TM0 continues
counting, overflows and then restarts counting from 0. Thus, if the value (M) after the CR00 change is smaller
than that (N) before the change, it is necessary to restart the timer after changing CR00.
