Fc9-type-16-icon.png Channel
SPI Channel selector 
Fc9-type-16-icon.png Prescale
Prescale option selector 
Fc9-type-5-icon.png MOSI
SPI Data Out Pin SDO - Also Known as Master Out Slave In (MOSI) when used in Master mode. 
Fc9-type-5-icon.png MISO
SPI Data In Pin SDI - Also Known as Master In Slave Out (MISO) when used in Master mode. 
Fc9-type-5-icon.png CLK
SPI Clock Pin CLK - The Clock signal is driven by the SPI master. 
Fc9-type-5-icon.png 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.  
Fc9-type-7-icon.png Use SHDN Pin
Allows the SHDN pin to be driven from an output pin on the microcontroller. If not used then tie the SHDN pin to VCC to allow the DAC to function. 
Fc9-type-7-icon.png Use LDAC Pin
Allows the LDAC pin to be driven from an output pin on the microcontroller. If not used then tie the LDAC pin to GND to allow the DAC to function.
