Application examples of the capture function
Used capture function, they can be applied in many ways, for example:
1. One-shot pulse output from external trigger pulse
2. Frequency measurement
3. Pulse width measurement
4. Time difference measurement
These four application examples are described in detail below.
1. One-shot pulse output from external trigger pulse
with the internal input clock, input the external trigger pulse from the TI8 pin,
and load the value of the up counter into capture register CAP8 at the rising
edge of the TI8 pin.
set the CAP8 value (c) plus a delay time (d) to TREG8 (= c + d), and set the
above set value (c + d) plus a one-shot pulse width (p) to TREG9 (= c + d + p).
When the interrupt INT8 occurs, the T8FFCR<EQ9T8 and EQ8T8>register
should be set to 11 so that the TFF8 inversion is enabled only when the up
counter value matches TREG8 or TREG9. When interrupt INTTR9 occurs,
this inversion will be disabled.
