10.4.1.1 Normal Mode

This is the normal operational mode, in which the receiver and driver are active, and LIN transmission up to the LIN specified maximum of 20 kbps is supported. The receiver detects the data stream on the LIN bus and outputs it on RXD for the LIN controller, where recessive on the LIN bus is a digital high, and dominate on the LIN bus is digital low. The driver transmits input data on TXD to the LIN bus. Normal mode is entered as EN transitions high while the TPIC1021A is in sleep or standby mode.
