Table 3-1.
This is the normal transmitting and receiving mode of the LIN interface in acoordance with the
LIN specification LIN 2.x. The voltage regulator is active and can source up to 50mA. The
undervoltage 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.
