9.4.1
If a timer 1 counter clock pulse is generated during the T3 state of a timer 1 counter (TCNT) write
cycle, the data write to T1CNT takes priority and the timer counter is not incremented. Figure 9.5
shows the operation in this case.
9.4.2
If bits CKS2 to CKS0 in the timer 1 control/status register (T1CSR) are rewritten while 8-bit timer
1 (TIM1) is running, the timer counter may not increment correctly. TIM1 must therefore be
stopped (by clearing the TME bit to 0) before rewriting bits CKS2 to CKS0.
