FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
SERIAL DATA CLOCK (SCLK)
MASTER OUT SLAVE IN (MOSI)
SCLK is the Serial Data Clock input pin of the serial
peripheral interface.
MOSI is the Master Out Slave In pin of the serial peripheral
interface. Control data from a microcontroller is received
through this pin.
MASTER IN SLAVE OUT (MISO)
CHIP SELECT (CS)
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.
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.
