3.13.4 Operation in Each Mode

In this example, the interrupt INTTB01 is set to be generated at fixed intervals. The
interval time is set in the timer register TB0RG1H/L.

(2) 16 bit event counter mode
In 16 bit timer mode as described in above, the timer can be used as an event
counter by selecting the external clock (TB0IN0 pin input) as the input clock. Up
counter (UC10) counts up at the rising edge of TB0IN0 input. To read the value of
the counter, first perform "software capture" once and read the captured value.
