LTC6810-1 Communication Problem with LTC6820 isoSPI and and Arduino.

Hi,

I am trying to communicate with LTC6810 with Arduino UNO (Linduino Code) Through LTC6820 iso-SPI board 2617A. I am not able to write and read the configuration register. Right now i am testing only with one slave board (Only one LTC6810-1). I am attaching the code here. Need help to start communication.  This is the error whenever i tries to write into LTC6810 configration registers. |Set or reset the gpio pins: 33

Written Configuration:
CFGA IC 1, 0x74, 0x52, 0x27, 0xA0, 0x00, 0x59, Calculated PEC: 0x44, 0x78

A PEC error was detected in the received data
Received Configuration
CFGA IC 1, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, Received PEC: 0xFF, 0xFF
