Table 15-2
15.2.1
This pad is connected to the single-wire LIN data bus.
15.2.2
This pin is the device LIN ground connection. It is used to sink currents related to the LIN Bus pin. A
de-coupling capacitor external to the chip (typically 220 pF, X7R ceramic) between LIN and LGND can
further improve the quality of this ground and filter noise.
15.2.3
External power supply to the chip.See device specification.
