Note:
When an interrupt is generated, clear the source flag in the interrupt handler.
If the interrupt enabled state is set without clearing the flag, another interrupt will be generated.

Select the count clock with the TPSC2 to TPSC0 bits
in TCR. When the external clock (TCLK) is selected,
specify the external clock edge with the CKEG1 and
CKEG0 bits in TCR.
Specify whether an interrupt is to be generated on
TCNT underflow with the UNIE bit in TCR.
When the input capture function is used, set the ICPE
bits in TCR, including specification of whether the
interrupt function is to be used.
Set a value in TCOR.
Set the initial value inTCNT.
Set the STR bit to 1 in TSTR to start the count.
