NORMAL MODE
compatible with the LIN protocol specification. The LIN bus
can transmit and receive information. The V
ON and the watchdog function can be enabled.
SLEEP AND STOP MODE
these modes are not inadvertently entered due to noise
issues during SPI transmission, a dedicated sequence must
be sent twice: data with the bits controlling the LIN bus and
the device mode.
