12.4 Interrupts
During interval timer operation, an overflow generates an interval timer interrupt (WOVI). The
interval timer interrupt is requested whenever the OVF bit is set to 1 in TCSR.
12.5 Usage Notes
Contention between TCNT Write and Increment: If a timer counter clock pulse is generated
during the T
incremented. See figure 12-8.
Changing CKS2 to CKS0 Values: Halt TCNT by clearing the TME bit to 0 in TCSR before
changing the values of bits CKS2 to CKS0.
