4. Functions
This chapter describes the different functions that can be implemented using the hardware and driver
together. Unless stated otherwise, the driver is assumed to be API-AIO(WDM).
Analog Output Function
Analog output processes are classified as follows:
- Simple Analog Output
- High-functional analog output
Simple Analog Output
When an analog output start command is executed by software, output data is set for one or more
channels, DA conversion is performed, and then the analog output operation is terminated.

The output voltage at 0ch is updated as illustrated above.
Analog outputs from multiple channels (Multiple channel outputs are
updated simultaneously.)
The output voltage from 0 to 2ch is updated as illustrated above.

* The analog output is finalized after the settling time after conversion is started.
The conversion speed is determined by the settling time per channel.
