The receiver is either waiting for an RF transmission or is receiving one. Two different processes are
possible, as determined by the values of the DME bit. A state diagram describes the sequence of operations
in each case.
11.1 Data Manager Disabled (DME=0)
Data manager disabled means that the SPI is deselected and raw data is sent directly on the MOSI line,
while SCLK remains at low level.
Two different processes are possible, as determined by the values of the SOE bit.
11.1.1 Data Manager Disabled and Strobe Pin Control
Raw received data is sent directly on the MOSI line.
For all states: At any time, a low level applied to CONFB forces the state machine to state 1, configuration
mode.

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 is output on the MOSI line.
Receive Mode
If the STROBE pin is tied to a high level before switching to receive mode,
the receiver does not go through an off or standby state.
STROBE = 1
