The LSC bit in the Physical Layer Control register offers a choice between two LIN slope
times, allowing communication up to 20 kbit/s (normal) or up to 10.4 kbit/s (low slope).
Setting the LDC bit in the Physical Layer Control register will increase the driver capability
of the LIN output stage. This feature is used in auto-addressing systems, where the
standard LIN 2.0 drive capability is insufficient.
The SBC handles and reports the following LIN-bus related failures:
These failure events force an interrupt to the microcontroller whenever the status changes
and the corresponding interrupt is enabled.
If the TXDL pin is clamped dominant for longer than t
disabled. After the TXDL pin becomes recessive the transmitter is reactivated
automatically when detecting bus activity or manually by setting and clearing the LTC bit.
