FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
Slave Status Byte
Contains the contents of the System Status Register ($0c)
independent of whether it is a write or read operation or which
register was selected.
Slave Data Byte
Contains the contents of selected register. During a write
operation it includes the register content prior to a write
operation.
SPI Register Overview
Table 6 summarizes the SPI Register addresses and the
bit names of each register.
ANALOG DIE I/OS
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
node. 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 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. Due to
excessive power dissipation in the transmitter, software is
advised to monitor this bit and turn the transmitter off
immediately.
TXD Pin
The TXD pin is the MCU interface to control the state of the
LIN transmitter (see Figure 2). When TXD is LOW, LIN output
is low (dominant state). When TXD is HIGH, the LIN output
MOSFET is turned off. The TXD pin has an internal pull-up
current source in order to set the LIN bus in recessive state
in the event, for instance, the microcontroller could not control
it during system power-up or power-down.
