10.3.1
It is recommended to first set the LIN Wake Capable Mode before setting the SBC Sleep or Stop Mode to avoid
missing a wake up event. The reason is identical to the CAN behavior. For additional information, see
Chapter
Do not change the Transciever setting with the same SPI command that is used to sent the device to Sleep Mode.
10.4
10.4.1
The LIN transceiver has a feature implemented to protect the battery from running out of charge in case of a bus
short to GND. When the LIN transceiver is switched to Wake capable or Off, the internal pull-up resistor is switched
off to prevent a large current from flowing to GND. In addition, the transceiver only wakes up on a dominant-to-
recessive edge on the LIN bus, so with the bus shorted to GND the transceiver does not wake up.
10.4.2
As required by LIN 2.1, an oscillator clock tolerance < 2% for the protocol handler is possible with LIN transceiver.
10.4.3
The device fulfills the Physical Layer Specification of LIN 2.1.
The device fulfills the Physical Layer Specification SAE J2602-2.
