Note: Pulse Width measure by setting “10” to TB1MOD<TB1CPM1:0>. The external interrupt
INT4 is generated in timing of falling edge of TB1IN0 input. In other modes, it is generated
in timing of rising edge of TB1IN0 input.

Pulse width measurement
keeping the 16-bit timer/event counter counting (Free running) with the prescaler
output clock input, external pulse is input through the TB1IN0 pin. Then the
capture function is used to load the UC12 values into TB1CP0H/L and
TB1CP1H/L at the rising edge and falling edge of the external trigger pulse
respectively. The interrupt INT4 occurs at the falling edge of TB1IN0.

and the second C1 at the second INT4 interrupt.
This mode allows measuring the high level width of an external pulse. While
The pulse width is obtained from the difference between the values of
For example, if the prescaler output clock is 0.8 μs and the difference between
Additionally, the pulse width that is over the UC12 maximum count time
The width of low level can be measured from the difference between the first C2
