* Special Configuration Recommended /
Mandatory for Marked NC Pins
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 (Serial Peripheral Interface) data output. When CS is high, pin is in the
high-impedance state.
SPI (Serial Peripheral Interface) data input.
SPI (Serial Peripheral Interface) clock Input.
SPI (Serial Peripheral Interface) chip select input pin. CS is active low.
Analog Multiplexer Output.
High side and low 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.
