Write Data to One Channel
The following example can be used if only one channel is to be written to, or if the outputs
are to be controlled individually. Don’t forget to either embed the sign information or use the
sign output bit for bipolar ranges.
Write Data to Both Channels
In the example below, if both selection channels are off, they will be updated with the same
data. Remember to either embed the sign information or use the sign output bit.
