LIN Transceiver
11.2.8
Slope Selection
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-Slope Mode. This complies
with SAE J2602 requirements.By default, the device works in LIN Normal-Slope Mode. The selection of LIN
Low-Slope Mode is done by an SPI bit
LIN_LSM
and will become effective as soon as CSN goes ‘HIGH’. Only the
LIN Slope is changed. The selection is accessible in SBC Normal Mode only.
11.2.9
Flash Programming via LIN
The device allows LIN flash programming, e.g. of another LIN Slave with a communication of up to 115 kBaud.
This feature is enabled by de-activating the slope control mechanism via a SPI command (bit LIN_FLASH) and
will become effective as soon as CSN goes ‘HIGH’. The SPI bit can be set in SBC Normal Mode.
Note:
It is recommended to perform flash programming only at nominal supply voltage VSHS = 13.5V to
ensure stable data communication.
