9.4.1 Normal Mode

If the EN pin is high at power up, the device powers up in normal mode and if low powers up in standby mode. In normal operational mode, the receiver and transmitter are active and the 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. A recessive signal on the LIN bus is a digital high and a dominant signal on the LIN bus is a digital low. The driver transmits input data from TXD to the LIN bus. Normal mode is entered as EN transitions high in Pin control mode or if reg0B[7:6] = 10 in SPI communication Mode. While in Pin control the device is in sleep or standby mode for > tMODE_CHANGE.
