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.

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
pullup 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.
