Definition
This pin is the receiver output of the LIN interface which reports the state of
the bus voltage to the MCU interface.
This pin is the transmitter input of the LIN interface which controls the state of
the bus output.
SPI data output. When CS is high, the pin is in the high-impedance state.
SPI data input.
SPI clock Input.
SPI chip select input pin. CS is active low.
Analog multiplexer output.
High side pulse width modulation input.
Bidirectional reset I/O pin - driven low when any internal reset source is
asserted. RST is active low.
Interrupt output pin, indicating wake-up events from Stop Mode or events from
Normal and Normal Request Modes. IRQ is active low.
No connect
