State 0: The receiver is off, but the strobe oscillator and the off counter are running. Forcing the STROBE
pin low maintains the system in this state.
State 0b: The receiver is kept on by the STROBE pin or the on counter. Raw data are output on the MOSI
line.
For all states: At any time, a low level applied to CONFB forces the state machine to state 1.
18.3.2 Data Manager Disabled and Strobe Pin Control
Raw received data are sent directly on the MOSI line.
State 5: The receiver is in standby/LVD mode. For further information, see
Mode.” A high level applied to STROBE forces the circuit to state 5b.
State 5b: The receiver is kept on by the STROBE pin. Raw data are output on the MOSI line.
For all states: At any time, a low level applied to CONFB forces the state machine to state 1.

configuration, the receiver is controlled internally by the strobe oscillator. However, external control via
the STROBE pin is still possible, and overrides the strobe oscillator command.
State 10: The receiver is off, but the strobe oscillator and the off counter are running. Forcing STROBE
pin to the low level maintains the system in this state.
State 11: The receiver is waiting for a valid ID. If an ID, or its complement, is detected, the state machine
advances to state 12; otherwise, the circuit goes back to state 10 at the end of the RON time, if STROBE≠1.
State 12: An ID or its complement has been detected. The data manager is now waiting for a header or its
complement. If neither a header, nor its complement, has been received before a time-out of 256 bits at
data rate, the system returns to state 10.
