When using ring format, write the data for one complete cycle of the output waveform before
starting operation.
You cannot write to the memory during its operation of analog output.
DA conversion data is output continuously in the sequence in which the ring format data is stored.
* Although the figure shows a single analog output channel, output from multiple channels is also
possible.
User buffer mode
- No overwriting
Data transfer stops after output reaches the end of the user buffer.
This memory format is useful if the sampling count is known in advance.
- Permit overwriting
Data transfer does not stop when output reaches the end of the user buffer.
Instead, transfer continues repeatedly until the conversion stop condition is established.
In this mode, the analog output operates like a function generator and continuously generates a
fixed waveform.
