Normal Mode

This is the normal transmitting and receiving mode of the LIN Interface, in accordance with LIN

specification 2.0. The V_CCvoltage regulator operates with a 5V output voltage, with a low toler-

ance of ±2% and a maximum output current of 50 mA.

If an undervoltage condition occurs, NRES is switched to low and the ATA6620N changes state

to Pre-normal mode. All features are available.
