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.

programming. The slew rate can be adapted with the bits
LINSL2:1 in the SPI Control Register. The initial slew rate is
optimized for 20kBit/s.

disconnected, with the LIN-PU bit in the SPI Control Register,
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.
