Memory format
This board uses device buffer transfer mode; it does not require software setup of the memory format.
- FIFO (First In First Out) format
Use FIFO format if you wish to output a continuous arbitrary analog output like that shown below.
When using FIFO format, writing of conversion data to memory is always performed from after the
most recent data and DA conversion is performed on the oldest data in memory.
You can write to memory during analog output operation.
An error occurs if the volume of data exceeds the memory size. However, this error does not stop
analog output if it is in progress.
- Ring format
Use ring format if you wish to output a repeated pattern like that shown below.
