Description

The command simultaneously sets 8 output I/O bits using the combination of the portNumber and outData values. The portNumber parameter specifies which group of 8 outputs to use where portNumber = 0 means outputs 0-7, portNumber = 1 means outputs 8-15, etc.

Once a portNumber is selected, a specific output pattern must be defined. The outData parameter may have a value between 0-255.

The table below shows some of the possible I/O combinations and their associated outData values assuming that portNumber is 0, and 1 accordingly.
