For devices that support the sampling
function of high-performance counter, it is possible to retrieve the count
value (Sampling) periodically by using Internal
Clock or External Clock.
It is necessary to perform sampling setting not only for using counter
in sampling mode but also for using a usual counter.
The sampling data is stored directly in the memory of the specified application.
In sampling mode, two or more continuous channels from channel 0 to a specified
channel of the counter are sampled at the same time.
Except for software start/stop, sampling can also start/stop by the rising
edge or falling edge of external signal. Moreover, It is possible to stop
sampling with specified times, or start/stop sampling when the count becomes
a specified value.
For sampling, except for condition setting of channel/start/clock/stop
mentioned above, it is also need to set items such as the buffer for storing
sampling data, sampling completion notification and specified time sampling
completion notification.
