Notes: *1 Including a transition from low to the stopped state (CKS1 = 0, CKS0 = 0), or a  
transition from the stopped state to low.  
*2 Including a transition from the stopped state to high.  
*3 Including a transition from high to the stopped state.  
*4The switching of clock sources is regarded as a falling edge, and therefore a TCNT  
clock pulse is generated and TCNT is incremented.
