A functional description of each pin can be found in the Functional Pin Description.

Pin Name

Formal Name

Definition

RXD

Receiver Output

This pin is the receiver output of the LIN interface which reports the state of

the bus voltage to the MCU interface.

TXD

Transmitter Input

This pin is the transmitter input of the LIN interface which controls the state of

the bus output.

MISO

SPI Output

SPI data output. When CS is high, the pin is in the high-impedance state.

MOSI

SPI Input

SPI data input.

SCLK

SPI Clock

SPI clock Input.

SPI Chip Select

SPI chip select input pin. CS is active low.

ADOUT0

Analog Output Pin 0

Analog multiplexer output.

PWMIN

PWM Input

High side pulse width modulation input.

RST

Internal Reset I/O

Bidirectional reset I/O pin - driven low when any internal reset source is

asserted. RST is active low.

IRQ

Internal Interrupt

Output

Interrupt output pin, indicating wake-up events from Stop mode or events from

Normal and Normal Request modes. IRQ is active low.
