10.2.2
The LIN transceiver offers a LIN Low Slope Mode for 10.4 kBaud communication and a LIN Normal Slope Mode
for 20 kBaud communication. The only difference is the behavior of the transmitter. In LIN Low Slope Mode, the
transmitter uses a lower slew rate to further reduce the EME compared to Normal Mode. This complies with SAE
J2602 requirements.
The selection is done for all transceivers at the same time so that the chip is working in either LIN Low slope Mode
or in LIN Normal Slope Mode. By default, the device works in LIN Low Slope Mode. The selection of LIN Normal
Slope Mode is done by an SPI word. The selection is accessible in SBC Normal Mode only.
10.2.3
In this mode, the LIN transceiver is completely disabled. Only an SPI command can reactivate the LIN cell. This
mode is accessible in SBC Normal, Stop, and Sleep Modes and is the default behavior in SBC Init Mode.
10.2.4
This mode, which can be used in SBC Stop, Sleep, Restart and Normal Modes by programming via SPI and is
automatically accessed in SBC Fail-Safe Mode, is used to monitor bus activities. A wake up signal on the bus
results in different behavior of the SBC, as described in
to LIN Normal Mode for communication. To enable the LIN Wakeable Mode after a wake via this LIN tranceiver,
the deticated LIN transceiver must be switched to LIN Normal Mode, LIN Receive Only Mode or LIN Off, before
switching to LIN Wakeable Mode again.

Wake-Up in SBC Sleep Mode
Wake-up is possible via a LIN message (filtering time t >
Restart Mode and from there to Normal Mode the corresponding RxD pins in set to LOW, see
microcontroller is able to detect the low signal on RxD and to read the wake source out of the “Wake Register
Interrupt” register (000) via SPI. No Interrupt is generated when coming out of Sleep Mode. The µC can now switch
the CAN transceiver into LIN Normal Mode via SPI to start communication.
Wake-Up in SBC Stop Mode
In SBC Stop Mode, if a wake-up is detected, it is signaled by the INT output and by the “WK LINx” SPI bit. It is also
signaled by RxDLINx put to low.The microcontroller should set the device to SBC Normal Mode, there is no
automatic transition to Normal Mode. In Normal Mode the transceiver can be enabled via SPI.
