properties like outputs, GPIO and PWM configuration for the PiXtend board are sent to the microcontroller<br>
in one block and states and values of all digital and analog inputs and outputs are received as response.<br>
This is the most efficient way to work with the microcontroller on the PiXtend board.<br>
<br>
In the beginning the auto_mode method should be called until the return value is 0 and the microcontroller's<br>
uc_state is 1, meaning the communication is working and the microcontroller has entered the 'Run' state.<br>
After that the auto_mode method does not need to be called on a regular basis, but when new values are needed<br>
or outputs have to be turned on or off.<br>

Example:<br>
if p.<a href="#Pixtend-auto_mode">auto_mode</a>() == 0 and p.uc_status == 1:<br>
p.relay0 = p.ON<br>
