9.7.1
Applications using the Capture Function
The capture function can be used to develop many applications, including those described below:
1. One-shot pulse output triggered by an external pulse
2. Frequency measurement
3. Pulse width measurement
4. Time difference measurement
An external pulse is input through the TBxIN0 pin. A trigger is generated at the rising of the external pulse by
using the capture function and the value of the up-counter is taken into the capture registers (TBxCP0).
pulse. This interrupt is used to set the timer registers (TBxRG0) to the sum of the TBxCP0 value (c) and the delay
time (d), (c + d), and set the timer registers (TBxRG1) to the sum of the TBxRG0 values and the pulse width (p)
of one-shot pulse, (c + d + p).[TBxRG1 change must be completed before the next match.]
enables triggering the timer flip-flop (TBxFF0) to reverse when TBxUC matches TBxRG0 and TBxRG1. This
trigger is disabled by the INTTBx interrupt after a one-shot pulse is output.
(With Delay)".
One-shot pulse output triggered by an external pulse
One-shot pulse output triggered by an external pulse is carried out as follows:
The 16-bit up-counter is made to count up by putting it in a free-running state using the prescaler output clock.
The CPU must be programmed so that an interrupt INTCAPx0 is generated at the rising of an external trigger
In addition, the timer flip-flop control registers(TBxFFCR<TBE1T1, TBE0T1>) must be set to "11". This
