AD conversion error
If the "device operating" status remains ON (without terminating conversion) for an extended period
of time, the driver regards that state as an operation error and sets this status to ON. This error stops
sampling.
 Sampling
The number of samplings of conversion data stored in memory can be obtained by the software
command.
 Transfer
The number of sampled items of input data stored in memory can be obtained by the software
command. This command can only be used in user buffer mode.
 Data acquisition
The conversion data stored in memory can be retrieved using a software command.
The figure below shows the correspondence between the sampling count and the conversion
channel for the conversion data stored in memory.
Conversion data is acquired differently depending on the memory format used.
