Note 1: Each of the four DAC8554 outputs controls a VOUTx and IOUTx channel-pair simultaneously. So, for
example, when writing to channel VOUT0, the associated IOUT0 channel will also be updated. Conversely,
when writing to channel IOUT0, the associated VOUT0 channel is also updated. Unused VOUTx and IOUTx
output channels should be left disconnected.
Note 2: The USB-3106 output voltage level defaults to 0V whenever the output voltage range is reconfigured.
The USB-3106 output voltage level will also default to 0V:
1) Whenever the host PC is reset, shut down or suspended.
2) If a reset command is issued to the device.
