7.4.1 Normal Mode

The EN pin controls the mode of the device. If the EN pin is high at power-up, the device powers-up in normal mode. If the EN is low at power-up, the device powers-up in standby mode. In normal mode, the receiver and transmitter are fully operational. The LIN transmitter transmits data from the LIN controller to the LIN bus up to the LIN specified maximum data rate of 20kbps. The LIN receiver detects the data stream on the LIN bus up to data rates of 100kbps, and outputs the data on RXD output for the LIN controller. Upon an EN pin transition from low to high, the TLIN821-Q1 transitions from sleep mode to normal mode in t ≥ tNOMINT.
