<h1>PicoNet.1 Physical Layer</h1>
The physical layer is one bidirectional open-drain line pulled up to +3.3V using a 1KOhm resistor.
Four symbols can be transmitted varying the time the bus is asserted down using an output mosfet:
<dl>
<dt>One
<dd>15ms down followed by 45ms up
<dt>Zero
<dd>45ms down followed by 15ms up
<dt>Break
<dd>90ms down followed by 30ms up
</dl>
