11.4.1
Each channel has a TCNT and TGR register. TCNT performs up-counting, and is also capable of
free-running operation, cycle counting, and external event counting.
Each TGR can be used as an input capture register or output compare register.
Always select MTU2 external pins set function using the pin function controller (PFC).
(1)
When one of bits CST0 to CST4 in TSTR is set to 1, the TCNT counter for the corresponding
channel begins counting. TCNT can operate as a free-running counter, periodic counter, for
example.
