4.3
In SBC Active Mode “LIN Sleep” the SBC’s current consumption is reduced by disabling the LIN transceiver.
This also means that the internal pull-up resistor of the LIN transceiver is turned off in SBC Active Mode “LIN
Sleep”. During this mode the LIN transceiver remains its wake-up capability in order to react on a remote frame or
wake-up pulse (specified in LIN Specification V2.0) from the master node or other slave nodes. In case of a wake-
up event via LIN message the (internal) RxD is pulled “low” and the “bus wake-up bit” within the SPI status word
is set. However, the LIN transceiver needs to be activated by switching to “SBC Active Mode”.

The LIN Receive-Only Mode (“LIN RxD-Only”) is designed for a special test procedure to check the bus
connections.
slave nodes. If the connection between node 1 and node 3 shall be tested, the nodes 2, 4 and 5 are switched into
LIN Receive-Only Mode. Node 1 and node 3 are in Active Mode. If node 1 sends a message (“remote frame”),
node 3 is the only node which is physically able to reply to the remote frame. The other nodes have their outputs
drivers disabled.
The main difference between the SBC Active Mode and the LIN Receive-Only Mode is that the LIN transmit
stage is automatically turned-off in LIN Receive-Only-Mode. However, the LIN receiver is still active in both modes.
