Time Difference Measurement
By using the capture function, the time difference between two events can be measured. Specifically,
the up-counter (UC6) is made to count up by putting it in a free-running state using the prescaler output
clock. The value of UC6 is taken into the capture register (TB6CP0) at the rising edge of the TB6IN0
pin input pulse. The INTC must be programmed to generate INT4 interrupt at this time.
The value of UC6 is taken into the capture register TB6CP1 at the rising edge of the TB6IN1 pin input
pulse. The INTC must be programmed to generate INT5 interrupt at this time.
The time difference can be calculated by multiplying the difference between TB6CP1 and TB6CP0 by
the clock cycle of an internal clock.
