Receive Mode
12.1.2 Data Manager Disabled and Strobe Oscillator Enabled
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.
12.2 Data Manager Enabled (DME=1)
The data manager is enabled. The SPI is master. The MC33696 sends the recovered clock on SCLK and
the received data on the MOSI line. Data is valid on falling edges of SCLK.
If an even number of bytes is received, the data manager may add an extra byte. The content of this extra
byte is random. If the data received do not fill an even number of bytes, the data manager will fill the last
byte randomly.

State 0:
The receiver is off, but the strobe oscillator and the off counter are running. Forcing the STROBE
pin low freezes the strobe oscillator and maintains the system in this state.
State 0b:
If STROBE pin is set to high level or the off counter reaches the ROFF value, the receiver is on.
Raw data is output on the MOSI line.
STROBE = 1

shows a typical transfer.
