Hi Experts,
I am trying to interface LTC6811 IC with microcontroller in SPI mode.
1. The SPI mode is with two wire isoSPI mode.
2. I have LTC6820 isoSPI serial interface IC to interface with microcontroller.

My question was LTC6811 is not giving any response when the CPOL = CPHA =1 of SPI mode (Both at the LTC6820 side and microcontroller SPI configuration) is set. All other CPOL / CPHA modes it is responding. Can you give some pointers why this is so ?

Regards
Sanes
