    FUNCTIONAL DEVICE OPERATION
    OPERATIONAL MODES
    ANALOG DIE INPUTS/OUTPUTS
    LIN PHYSICAL LAYER
    The LIN bus pin provides a physical layer for single-wire
    communication in automotive applications. The LIN physical
    layer is designed to meet the LIN physical layer specification.
    The LIN driver is a low side MOSFET with internal current
    limitation and thermal shutdown. An internal pull-up resistor
    with a serial diode structure is integrated, so no external pull-
    up components are required for the application in a slave
    mode. The fall time from dominant to recessive, and the rise
    time from recessive to dominant is controlled. The symmetry
    between both slew rate controls is guaranteed.
    The slew rate can be selected for optimized operation at
    10 and 20 kBit/s, as well as high baud rates for test and
    programming. The slew rate can be adapted with 2 bits
    SRS[1:0] in the System Control Register. The initial slew rate
    is optimized for 20 kBit/s.
    The LIN pin offers high susceptibility immunity level from
    external disturbance, guaranteeing communication during
    external disturbance.
    The LIN transmitter circuitry is enabled by setting the
    PSON bit in the System Control Register (SYSCTL).
    If the transmitter works in the current limitation region, the
    LINCL bit in the System Status Register (SYSSTAT) is set
    and the LIN transceiver is disabled after a certain time.
    For improved performance and safe behavior when the
    LIN bus shorts to Ground, or LIN bus leakage during low
    power mode, the internal pull-up resistor on the LIN pin is
    disconnected from VSUP and a small current source keeps
    the LIN bus at recessive level. In case of a LIN bus short to
    GND, this feature will reduce the current consumption in
    STOP and SLEEP modes.
    Figure 16. LIN Interface
    TXD Pin
    The TXD pin is the MCU interface to control the state of the
    LIN transmitter (see Figure 2, page 2). When TXD is LOW,
    the LIN pin is low (dominant state). When TXD is HIGH, the
    LIN output MOSFET is turned off (recessive state). The TXD
    pin has an internal pull-up current source in order to set the
    LIN bus to recessive state in the event, for instance, the
    microcontroller could not control it during system power-up or
    power-down.
