Data transfer method
A device buffer mode is available, which uses the device's or driver's conversion data storage memory.
- Device buffer mode
The application output data is first stored in the device buffer (memory on the device itself or in
the driver).
When conversion starts, the device starts outputting the output data.
The device buffer can operate as FIFO or RING memory.
The device buffer mode provides a function that allows the number of items of conversion data
using the number of sampling times as a unit to set the number of items of conversion data
directly using the voltage.
