•
When the internal RAM is selected and the external sampling is set, the data is read in 1 μs as internal
processing, an external pulse is used, and the next internal processing data is write to the memory .
Therefore, the capturing interval is at maximum 1 μs and the maximum input error is 1 μs.
Please use the external sampling function within the range where this error is not a problem .
