11.4 Operation
11.4.1 Basic Functions
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) Counter Operation
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.
(a) Example of count operation setting procedure
Figure 11.3 shows an example of the count operation setting procedure.
