Note: When using an analog input, the pull-up should be Off.
Low Side Current Sink Output
Low side current sink output, for example to drive a relay, is only available using
I/O3 on the power connector.

Note: When using low side current sink output, the pull-up should be Off.
The I/O can typically sink 400 mA, but this can vary depending on factors such as
temperature.
