L9963E does not work in direct SPI mode (SPIEN = 1)

I am using EVAL-9963EFrom datasheet, when SPIEN pin of L9963E is connected to VCOM and R43, R46, R57, R138, R139, R140, R141, R143 are assembled, L9963E is now ready to use direct SPI (normal SPI without isolation). 1 MCU communicates with 1 L9963E o...

Getting real time ADC data out of STPM32

Apart from the V_RMS, I_RMS, power and energy (all aggregated), is it possible to output the ADC readings real time over SPI? I am looking to get 8k samples of I and V out of it. As of it was a pure ADC, with the filtering, but without the calculatio...
