State 20:
The receiver is in standby/LVD mode. For further information, see
Mode.” A high level applied to STROBE forces the circuit to state 21.
State 21:
The circuit is waiting for a valid ID. If an ID, or its complement, is detected, the state machine
advances to state 22; if not, the state machine will remain in state 21, as long as STROBE is high.
State 22:
If a header, or its complement, is detected, the state machine advances to state 23. If not, the state
machine will remain in state 22, as long as STROBE is high.
State 23:
A header or its complement has been received; data and clock signals are output on the SPI port
until an EOM indicates the end of the data sequence. If the complement of the header has been
