10.4.1
Each channel has a TCNT and TGR register. TCNT performs up-counting, and is also capable of
free-running operation, periodic counting, and external event counting.
Each TGR can be used as an input capture register or output compare register.
(1)
When one of bits CST0 to CST5 is set to 1 in TSTR, the TCNT counter for the corresponding
channel starts counting. TCNT can operate as a free-running counter, periodic counter, and so on.

Figure 10.2 shows an example of the count operation setting procedure.

Select the counter clock with
bits TPSC2 to TPSC0 in TCR.
At the same time, select the
input clock edge with bits
CKEG1 and CKEG0 in TCR.
For periodic counter operation,
select the TGR to be used as
the TCNT clearing source with
bits CCLR2 to CCLR0 in TCR.
Designate the TGR selected in
[2] as an output compare
register by means of TIOR.
Set the periodic counter cycle in
the TGR selected in [2].
Set the CST bit in TSTR to 1 to
start the counter operation.
