(4) Contention between Compare-Match A and Compare-Match B: 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 8-4.

(5) Incrementation Caused by Changing of Internal Clock Source: 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 (CKS2 to CKS0) are rewritten, as shown in table 8-5.
