FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
For improved performance and safe behavior in case of
LIN bus short to Ground or LIN bus leakage during low power
mode the internal pull-up resistor on the LIN terminal 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 Terminal
The TXD terminal is the MCU interface to control the state
of the LIN transmitter (see
Figure 2
, page
2
). When TXD is
LOW, the LIN terminal is low (dominant state). When TXD is
HIGH, the LIN output MOSFET is turned off (recessive state).
The TXD terminal 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.
RXD Terminal
The RXD transceiver terminal is the MCU interface, which
reports the state of the LIN bus voltage. LIN HIGH (recessive
state) is reported by a high level on RXD, LIN LOW (dominant
state) by a low level on RXD.
STOP Mode and Wake-up Feature
During STOP mode operation the transmitter of the
physical layer is disabled and the internal pull-up resistor is
disconnected from VSUP and a small current source keeps
the LIN terminal in recessive state. The receiver is still active
and able to detect wake-up events on the LIN bus line.
If the LIN interrupt is enabled (LINIE bit in the Interrupt
Mask register is set), a dominant level longer than T
propWL
followed by an rising edge will set the LINIF flag and generate
an interrupt which causes a system wake-up (see
Figure 8
,
page
19
)
SLEEP Mode and Wake-up Feature
During SLEEP mode operation the transmitter of the
physical layer is disabled and the internal pull-up resistor is
disconnected from VSUP and a small current source keeps
the LIN terminal in recessive state. The receiver is still active
to be able to detect wake-up events on the LIN bus line.
A dominant level longer than T
propWL
followed by an rising
edge will generate a system wake-up (reset) and set the
LINWF flag in the Reset Status register (RSR). Also see
Figure 9

19
