There are a number of alternate IO functions that can be enabled. These functions override
the default IO function given in section 4.4, and described in the LED table of section 2.3.
If no bits are set for a particular PIO pin, that pin is available to be used as general purpose
input or output, based on the IOMASK setting.
Bit
There are a number of print functions that can be enabled to assist in debugging the operation
and status of the module. The following command is used to control these printouts.

Once the configuration has been checked, this can then be turned off so that these messages
do not interfere with the datastream.
