Event
“Event” works as a function for reporting the occurrence of a certain board state to the application.
The following events can be used in combination depending on the specifications and purpose of the
application.
-
“DA conversion start condition satisfied” event
This event occurs when the DA conversion start condition is satisfied. The event is nullified when
the conversion start condition is “software”.
-
“Repeat end” event
This even occurs whenever a repetition is completed.
-
“End of device operation” event
This event occurs when the entire operation including repetitions is completed.
-
“Specified number of output samples complete" event
This event occurs when the number of output samples specified by software have been completed.
This event is used when the device buffer mode is used for data transfer.
-
Specified number of transfers event
This event occurs each time a specified number of samples (set by software) has been completed.
When FIFO format is used, the event occurs when the remaining number of samples falls below a
specified level. The event occurs repeatedly as long as this condition is satisfied.
When ring memory format is used, the event occurs when the number of samples output from
memory reaches a specified value. The event occurs for the specified number of repetitions.
This event is used when the user buffer mode is used for data transfer.
-
Sampling clock error event
This event occurs when conversion stops as an error occurs due to a sampling clock period that is
too short.
-
DA conversion error event
This event occurs when conversion stops due to a DA conversion error.
2. Starting/Stopping Operation
Analog output operation is started by a software command (the analog output start command).
Similarly, you can stop analog output at any time using a software command (the analog output stop
command).
