FUNCTIONAL DESCRIPTION

FUNCTIONAL PIN DESCRIPTION

the state of CANH and CANL is reported through RXD output.

A 60

Ω termination resistor is connected between CANH and

CANL pins.

SERIAL DATA CLOCK (SCLK)

SCLK is the Serial Data Clock input pin of the serial

peripheral interface.

MASTER IN SLAVE OUT (MISO)

MISO is the Master In Slave Out pin of the serial peripheral

interface. Data is sent from the SBC to the microcontroller

through the MISO pin.

MASTER OUT SLAVE IN (MOSI)

MOSI is the Master Out Slave In pin of the serial peripheral

interface. Control data from a microcontroller is received

through this pin.

CHIP SELECT (CS)

CS is the Chip Select pin of the serial peripheral interface.

When this pin is LOW, the SPI port of the device is selected.

WATCHDOG OUTPUT (WDOG)

The Watchdog output pin is asserted LOW to flag that the

software watchdog has not been properly triggered.
