9.6.4
If identical time constants are written in TCORA and TCORB, causing compare-match A and B to
occur simultaneously, any conflict between the output selections for compare-match A and B is
resolved by following the priority order in table 9.4.

9.6.5
When an internal clock source is changed, the changeover may cause the timer counter to
increment. This depends on the time at which the clock select bits (CKS1, CKS0) are rewritten, as
shown in table 9.5.
The pulse that increments the timer counter is generated at the falling edge of the internal clock
source signal. If clock sources are changed when the old source is high and the new source is low,
as in case no. 3 in table 9.5, the changeover generates a falling edge that triggers the TCNT clock
pulse and increments the timer counter.
Switching between an internal and external clock source can also cause the timer counter to
increment.
