LIN PHYSICAL LAYER
communication in automotive applications. The LIN physical
layer is designed to meet the LIN physical layer specification
and has the following features:
Slew Rate Selection
10.4 and 20 kBit/s as well as a fast baud rate for test and
programming. The slew rate can be adapted with the bits
LSR1:0 in the LIN control register (LINCR). The initial slew
rate is optimized for 20 kBit/s.

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 slopes is guaranteed.

LIN Pull-up Disable In Stop and Sleep Mode
LIN bus short to ground or LIN bus leakage during Low Power
mode the internal pull-up resistor on the LIN pin can be
disconnected by clearing the LINPE bit in the MCR. The bit
LINPE also changes the bus wake-up threshold (
