4.
Used capture function, they can be applicable in many ways, for example:
1.
One-shot pulse output from external trigger pulse
Frequency measurement
Pulse width measurement
Measurement of difference time
input the external trigger pulse from TB1IN0 pin, and load the value of up
counter into capture register TB1CP0H/L at the rise edge of external trigger
pulse.
set the TB1CP0H/L value (c) plus a delay time (d) to TB1RG0H/L (= c + d), and set
the above set value (c + d) plus a one-shot width (p) to TB1RG1H/L (= c + d + p).
And, set “11” to timer flip-flop control register TB1FFCR<TB1E1T1, TB1E0T1>.
Set to trigger enable for be inverted timer flip-flop TB1FF0 by UC12 matching
with TB1RG0H/L and with TB1RG1H/L. When interrupt INTTB11 occurs, this
inversion will be disabled after one-shot pulse is output.
One-shot pulse output from external trigger pulse
Set the up counter UC12 in free-running mode with the internal input clock,
When the interrupt INT4 is generated at the rise edge of external trigger pulse,
The (c), (d), and (p) correspond to c, d, and p in Figure 3.8.12.

Set the counter in free-running mode.
c
Set it to disables that
inversion caused by
loading into TB1CP1H/L.
Load into capture register 1 (TB1CP0H/L)
and generate INT4.
