FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
RXD Pin
The RXD transceiver pin 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 pin 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 tPROPWL
followed by an rising edge will set the LINIF flag and generate
an interrupt which causes a system wake-up (see Figure 8,
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. A small current source keeps the
LIN pin 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 tPROPWL 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
A0 INPUT AND ANALOG MULTIPLEXER
A0 - Analog Input
Input A0 is an analog input used for reading switches or as
analog inputs for potentiometers, NTC, etc.
A0 is internally connected to the analog multiplexer. This
pin offers a switchable current source. To read the Analog
Input the pin, it has to be selected with the SS[3:0] bits in the
A0MUCTL register.
Figure 17. Analog Input and Multiplexer
A0 Current Source
The pin A0 provides a switchable current source, to be
able to read in switches, NTC, etc., without the need of an
additional supply line for the sensor. The overall enable of
this feature is done by setting the PSON bit in the System
Control register. In addition, the pin has to be selected with
the SS[3:0] bits. The current source can be enabled with the
CSON Bit, and adjusted with the bits CSSEL[1:0].
The CSSEL[1:0] bit’s four different current values can be
selected (40, 120, 320 and 800A). This function is halted
during STOP and SLEEP mode operations.
The current source is derived from the VDD voltage and is
constant up to an output voltage of ~4.75 V.
