ADS1293: SPI configuration mode

Part Number: ADS1293

Hi Support, 

I'm using STM32L4 microcontroler and ADS1293 sensor using SPI. 

SPI baudrate is 20 MBit/s. 

I'm asking for the SPI configuration mode? 

ie: CPHA (0 or 1) and  CPOL (0 or 1) 

Best regards.

    Hello Ghada,

    Thank you for your interest in our ADS1293.

    The SPI interface uses CPHA = 0, CPOL = 0 (MODE 0). This means that SCLK is expected to idle low. The rising edge will be used to latch the data, while the falling edge will be used to shift the data.
