Every OPTION of the kbusdemo requires an address since every kbusdemo
action, which is specified by the OPTION, is linked to a certain address in the
process image.
Example:
./kbusdemo
The bit for the output address 0.0 in the process image is set to TRUE
./kbusdemo
The bit for the output address 1.7 in the process image is set to FALSE
./kbusdemo
Reads the data at input byte 0
Output:
The first byte has the following format: IN[Byte] binary - || IN[Byte]
hexadecimal output
