3.3.20.1 Normal Mode

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

voltage regulator is active and can source up to 85mA. The under voltage detection is activated. The watchdog needs a

trigger signal from NTRIG to avoid resets at NRES. If NRES is switched to low, the IC changes its state to fail-safe mode.
