Product data sheet
6.7.4.3 GND shift detection
6.8.1.1 Active mode
6.8.1 Mode control
6.8 LIN transceiver
The SBC can detect ground shifts in reference to the CAN bus. Two different ground shift
detection levels can be selected with the GSTHC bit in the System Configuration register.
The failure can be read out in the System Diagnosis register. Any detected or recovered
GND shift event is signalled with an interrupt, if enabled.
The integrated LIN transceiver of the UJA1061 is a LIN 2.0 compliant transceiver. The
transceiver has the following features:
The controller of the LIN transceiver provides two modes of operation: Active mode and
Off-line mode; see
current, but wake-up events will be recognized by the separate wake-up receiver.
In Active mode the LIN transceiver can transmit data to and receive data from the LIN bus.
To enter Active mode the LMC bit must be set in the Physical Layer Control register and
the SBC must be in Normal mode or Flash mode.
