Hello all,
I am using NXP's  TJA1028T/5V0/20/1J  LIN transceiver with STM8 board. To bring LIN transceiver into "Normal Mode", is it mandatory to feed 5V supply to EN pin and VBATT pin of transceiver?  I have fed 3.3V to EN pin and 3V to VBATT pin. It is not working. Other pins I have connected correctly.


Note:  The LIN transceiver is activated when the TJA1028 enters Normal mode.In Normal mode, the transceiver can transmit and receive data via the LIN bus. Thereceiver detects data streams on the LIN pin and transfers them to the microcontroller viapin RXD. LIN recessive is represented by a HIGH level on RXD, LIN dominant by a LOWlevel.  (This is mentioned in data sheet)
