	MOSI
SPI Data Out Pin SDO - Also Known as Master Out Slave In (MOSI) when used in Master mode.
	MISO
SPI Data In Pin SDI - Also Known as Master In Slave Out (MISO) when used in Master mode.
	CLK
SPI Clock Pin CLK - The Clock signal is driven by the SPI master.
	CS / SS
Chip Select / Slave Select Pin Master Mode: General purpose output pin used to select the remote SPI device. Slave Mode: Hardware chip select pin input used to select the SPI device.
	Use IRQ
No: Use polling of the status register to determine when an ADC sample is complete. Yes: Use the IRQ interrupt pin to determine when an ADC sample is complete.
	IRQ Pin
Connected to the IRQ pin of the device, goes low on an interrupt event such as sample complete.
	Simulations
	Simulate Comms
No: Simulation is done using panel sliders. Yes: Send SPI data via API interface and show real time data using panel sliders.
