STATE MACHINE WITH STROBE PIN CONTROL
Programming SOE=0 sets ROMEO2 to state 6. The circuit is in Sleep mode.
A high level applied on STROBE sets the circuit into state 7. If an ID or its complement is detected, the state
machine advances to state 8. If not, it will stay in state 7 as long as STROBE is high.
After ID or its complement detection, ID byte is sent to the microcontroller on MOSI line at 310kBd. This warns
the microcontroller that data are received which means that an high level has to be maintained on STROBE. At
any time a low level applied on STROBE sets the circuit into state 6.
