If Header or its complement is detected, the state machine advances to state 10. If not, it will stay in state 9 as
long as STROBE is high.
If Header has been received, data and clock signals are output on the SPI port. If the complement of Header has
been received, output data are complemented too. At any time a low level applied on STROBE sets the circuit
into state 6, after the current byte is fully transmitted.
If data are received after a End of Message they are output on the MOSI pin without clock recovery.
At any time, a low level applied on RESETB for more than one Ts forces the state machine to state 1. When the
transition condition from one state to the next one is fulfilled, the transition time is one Ts except reaching state 6.
The transition time for reaching state 6 is 2
low when in state 10).
