Memory must be set to ring format if a number of repetitions is to be specified.
(The number of repetitions cannot be specified for FIFO memory format.)
The number of repetitions is set by software and sampling is repeated for the specified number of
times. You can also specify that operation continue indefinitely. If set to repeat indefinitely, analog
output operation is stopped by outputting an analog output stop command by software.
Setting data
Use a software command to save the data in memory.
The figure below shows the relationship between the conversion data stored in memory and the
sampling count and conversion channels.
The procedure for setting the conversion data is different depending on the memory format being used.
- Procedure for FIFO format
When using FIFO format, setting data to memory is always performed from the most recent data.
New data can be added during conversion.
- Procedure for RING format
When using ring format, a ring memory area large enough for the data to be set is reserved.
Data cannot be modified during DA conversion.
