4.1 Normal Mode

This is the normal transmitting and receiving mode of the LIN interface, in accordance with LIN specification 2.x. The VCC

voltage regulator operates with a 3.3V/5V output voltage, with a low tolerance of ±2% and a maximum output current of

85mA.

If an undervoltage condition occurs, NRES is switched to low and the IC changes its state to fail-safe mode.
